Layouts with a single window other than "MERGED" do not work (e.g.
"LOCAL" or "MERGED+LOCAL").
This is because as the documentation of bufdo says:
The last buffer (or where an error occurred) becomes the current
buffer.
And we do always do bufdo the end.
Additionally, we do it only once, when it should be per tab.
Fix this by doing it once per tab right after it's created and before
any buffer is switched.

When vimdiff3 was added in 7c147b77d3 (mergetools: add vimdiff3 mode,
2014-04-20), the description made clear the intention:
It's similar to the default, except that the other windows are
hidden. This ensures that removed/added colors are still visible on
the main merge window, but the other windows not visible.
However, in 0041797449 (vimdiff: new implementation with layout support,
2022-03-30) this was broken by generating a command that never creates
windows, and therefore vim never shows the diff.
The layout support implementation broke the whole purpose of vimdiff3,
and simply shows MERGED, which is no different from simply opening the
file with vim.
In order to show the diff, the windows need to be created first, and
then when they are hidden the diff remains (if hidenoff isn't set), but
by setting the `hidden` option the initial buffers are marked as hidden
thus making the feature work.

* js/vimdiff-quotepath-fix:
mergetool(vimdiff): allow paths to contain spaces again
In 0041797449 (vimdiff: new implementation with layout support,
2022-03-30), we introduced a completely new implementation of the
`vimdiff` backend for `git mergetool`.
In this implementation, we no longer call `vim` directly but we
accumulate in the variable `FINAL_CMD` an arbitrary number of commands
for `vim` to execute, which necessitates the use of `eval` to split the
commands properly into multiple command-line arguments.
That same `eval` command also needs to pass the paths to `vim`, and
while it looks as if they are quoted correctly, that quoting only
reaches the `eval` instruction and is lost after that, therefore paths
that contain whitespace characters (or other characters that are
interpreted by the POSIX shell) are handled incorrectly.
This is a simple reproducer:
git init -b main bam-merge-fail
cd bam-merge-fail
echo a>"a file.txt"
git add "a file.txt"
git commit -m "added 'a file.txt'"
echo b>"a file.txt"
git add "a file.txt"
git commit -m "diverged b 'a file.txt'"
git checkout -b c HEAD~
echo c>"a file.txt"
git add "a file.txt"
git commit -m "diverged c 'a file.txt'"
git checkout main
git merge c
git mergetool --tool=vimdiff
With Git v2.37.0/v2.37.1, this will open 7 buffers, not four, and not
display the correct contents at all.
To fix this, let's not expand the variables containing the path
parameters before passing them to the `eval` command, but let that
command expand the variables instead.

'vim' has two configuration options ('splitbelow' and 'splitright') that
change the way the 'split' command behaves. When they are set, the
commands that the layout engine generates no longer work as expected.
In order to fix this we can append special keyword 'leftabove' to each
'split' and 'vertical split' subcommand found inside the command string
generated by the layout engine.
This works because whatever comes after 'leftabove' will temporally
ignore settings 'splitbelow' and 'splitright'.

Running 'git {merge,diff}tool --tool-help' now also prints usage
information about the vimdiff tool (and its variants) instead of just
its name.
Two new functions ('diff_cmd_help()' and 'merge_cmd_help()') have been
added to the set of functions that each merge tool (ie. scripts found
inside "mergetools/") can overwrite to provided tool specific
information.
Right now, only 'mergetools/vimdiff' implements these functions, but
other tools are encouraged to do so in the future, specially if they
take configuration options not explained anywhere else (as it is the
case with the 'vimdiff' tool and the new 'layout' option)
Note that the function 'show_tool_names', used in the implementation of
'git mergetool --tool-help', is also used in Documentation/Makefile to
generate the list of allowed values for the configuration variables
'{diff,merge}.{gui,}tool'. Adjust the rule so its output is an Asciidoc
"description list" instead of a plain list, with the tool name as the
item and the newly added tool description as the description.

When running 'git mergetool -t vimdiff', a new configuration option
('mergetool.vimdiff.layout') can now be used to select how the user
wants the different windows, tabs and buffers to be displayed.
If the option is not provided, the layout will be the same one that was
being used before this commit (ie. two rows with LOCAL, BASE and COMMIT
in the top one and MERGED in the bottom one).
The 'vimdiff' variants ('vimdiff{1,2,3}') still work but, because they
represented nothing else than different layouts, are now internally
implemented as a subcase of 'vimdiff' with the corresponding
pre-configured 'layout'.
Again, if you don't set "mergetool.vimdiff.layout" everything will work

others (even if you don't/shouldn't notice it):
- git mergetool -t vimdiff

Users often use "git difftool HEAD^" to review their work, and have
"mergetool.prompt" set to false so that difftool does not prompt them
before diffing each file.
This is very convenient because users can see all their diffs by
reviewing the xxdiff windows one at a time.
A problem occurs when xxdiff encounters some binary files.
It can segfault and return exit code 128, which is special-cased
by git-difftool-helper as being an extraordinary situation that
aborts the process.
Suppress the exit code from xxdiff in its diff_cmd() implementation
when we see exit code 128 so that the GIT_EXTERNAL_DIFF loop continues
on uninterrupted to the next file rather than aborting when it
encounters the first binary file.

This adds yet another vimdiff/gvimdiff variant and presents conflicts as
a two-way diff between 'LOCAL' and 'REMOTE'. 'MERGED' is not opened
which deviates from the norm so usage text is echoed as a Vim message on
startup that instructs the user with how to proceed and how to abort.
Vimdiff is well-suited to two-way diffs so this is an option for a more
simple, more streamlined conflict resolution. For example: it is
difficult to communicate differences across more than two files using
only syntax highlighting; default vimdiff commands to get and put
changes between buffers do not need the user to manually specify
a source or destination buffer when only using two buffers.
Like other merge tools that directly compare 'LOCAL' with 'REMOTE', this
tool will benefit when paired with the new `mergetool.hideResolved`
setting.

`setup_tool` would notice that after stripping off the trailing digit,
it finds a match in `mergetools/` (the `bc` file), source it, and then
the alias would not match the list offered by the `list_tool_variants`
function, and simply exit without doing anything, but pretending

feature, rather than relying on a timestamp heuristic that is
unforgiving to users that save in-progress merge files.

Built-in merge tools contain a hard-coded assumption about
whether or not a tool's exit code can be trusted to determine
the success or failure of a merge. Tools whose exit codes are
not trusted contain calls to check_unchanged() in their
merge_cmd() functions.
A problem with this is that the trustExitCode configuration is
not honored for built-in tools.
Teach built-in tools to honor the trustExitCode configuration.
Extend run_merge_cmd() so that it is responsible for calling
check_unchanged() when a tool's exit code cannot be trusted.
Remove check_unchanged() calls from scriptlets since they are no
longer responsible for calling it.
When no configuration is present, exit_code_trustable() is
checked to see whether the exit code should be trusted.
The default implementation returns false.
Tools whose exit codes can be trusted override
exit_code_trustable() to true.

Originally, with no base, Git gave P4Merge $LOCAL as a dummy base:
p4merge "$LOCAL" "$LOCAL" "$REMOTE" "$MERGED"
Commit 0a0ec7bd changed this to:
p4merge "empty file" "$LOCAL" "$REMOTE" "$MERGED"
to avoid the problem of being unable to save in some circumstances with
similar inputs.
Unfortunately this approach produces much worse results on differing
inputs. P4Merge really regards the blank file as the base, and once you
have just a couple of differences between the two branches you end up
with one a massive full-file conflict. The 3-way diff is not readable,
and you have to invoke "difftool MERGE_HEAD HEAD" manually to get a
useful view.
The original approach appears to have invoked special 2-way merge
behaviour in P4Merge that occurs only if the base filename is "" or
equal to the left input. You get a good visual comparison, and it does
not auto-resolve differences. (Normally if one branch matched the base,
it would autoresolve to the other branch).
But there appears to be no way of getting this 2-way behaviour and being
able to reliably save. Having base==left appears to be triggering other
assumptions. There are tricks the user can use to force the save icon
on, but it's not intuitive.
So we now follow a suggestion given in the original patch's discussion:
generate a virtual base, consisting of the lines common to the two
branches. This is the same as the technique used in resolve and octopus
merges, so we relocate that code to a shared function.
Note that if there are no differences at the same location, this
technique can lead to automatic resolution without conflict, combining
everything from the 2 files. As with the other merges using this
technique, we assume the user will inspect the result before saving.

Reverse LOCAL and REMOTE when invoking P4Merge as a mergetool, so that
the incoming branch is now in the left-hand, blue triangle pane, and the
current branch is in the right-hand, green circle pane.
This change makes use of P4Merge consistent with its built-in help, its
reference documentation, and Perforce itself. But most importantly, it
makes merge results clearer. P4Merge is not totally symmetrical between
left and right; despite changing a few text labels from "theirs/ours" to
"left/right" when invoked manually, it still retains its original
Perforce "theirs/ours" viewpoint.
Most obviously, in the result pane P4Merge shows changes that are common
to both branches in green. This is on the basis of the current branch
being green, as it is when invoked from Perforce; it means that lines in
the result are blue if and only if they are being changed by the merge,
making the resulting diff clearer.
Note that P4Merge now shows "ours" on the right for both diff and merge,
unlike other diff/mergetools, which always have REMOTE on the right.
But observe that REMOTE is the working tree (ie "ours") for a diff,
while it's another branch (ie "theirs") for a merge.
Ours and theirs are reversed for a rebase - see "git help rebase".
However, this does produce the desired "show the results of this commit"
effect in P4Merge - changes that remain in the rebased commit (in your
branch, but not in the new base) appear in blue; changes that do not
appear in the rebased commit (from the new base, or common to both) are
in green. If Perforce had rebase, they'd probably not swap ours/theirs,
but make P4Merge show common changes in blue, picking out our changes in
green. We can't do that, so this is next best.

Update mergetools to work better with newer merge helper tortoise ships.
* ss/mergetools-tortoise:
mergetools: teach tortoisemerge to handle filenames with SP correctly
mergetools: support TortoiseGitMerge
TortoiseGitMerge, unlike TortoiseMerge, can be told to handle paths
with spaces in them by using -option "$FILE" (not -option:"$FILE",
which does not work for such paths) syntax.
This change was necessary because of MSYS path mangling [1], the ":"
after the "base" etc. arguments to TortoiseMerge caused the whole
argument instead of just the file name to be quoted in case of file
names with spaces. So TortoiseMerge was passed
"-base:new file.txt"
instead of
-base:"new file.txt"
(including the quotes). To work around this, TortoiseGitMerge does not
require the ":" after the arguments anymore which fixes handling file
names with spaces [2] (as written above).

Remove the exceptions for "vim" and "defaults" in the mergetool library
so that every filename in mergetools/ matches 1:1 with the name of a
valid built-in tool.
Define the trivial fallback definition of shell functions in-line in
git-mergetool-lib script, instead of dot-sourcing them from another
file. The result is much easier to follow.
