unpack_trees() merges two trees (the current HEAD and the destination
commit) when switching to another branch, checking and updating the index
entry where the destination differs from the current HEAD. It merges three
trees (the common ancestor, the current HEAD and the other commit) when
performing a three-way merge, checking and updating the index entry when
the merge result differs from the current HEAD. It does so by walking the
input trees in parallel all the way down to the leaves.
One common special case is a directory is identical across the trees
involved in the merge. In such a case, we do not have to descend into the
directory at all---we know that the end result is to keep the entries in
the current index.
This optimization cannot be applied in a few special cases in
unpack_trees(), though. We need to descend into the directory and update
the index entries from the target tree in the following cases:
- When resetting (e.g. "git reset --hard"); and
- When checking out a tree for the first time into an empty working tree
(e.g. "git read-tree -m -u HEAD HEAD" with missing .git/index).

Unlike bash and ksh, dash passes through hexadecimal \xcc escapes.
So when run with dash, these tests *pass* (since '\xcc' is a perfectly
reasonable filename) but they are not testing what was intended.
Use octal escapes instead, in the spirit of v1.6.1-rc1~55^2
(2008-11-09).

Some shells, for example dash versions older than 0.5.4, need to
spell a variable reference as '$N' rather than 'N' in an arithmetic
expansion. In order to avoid the syntax error, we change the
offending variable reference from 'i' to '$i' in function scramble.
There is nothing bash specific to this test script (and we shouldn't
have any bash dependent test). Fix its shebang line.

When blaming files in the working tree, the filespec is marked with
!sha1_valid, as we have not given the contents an object name yet. The
function to cache textconv results (keyed on the object name), however,
didn't check this condition, and ended up on storing the cached result
under a random object name.

I have a git repository with lots of .doc and .pdf files. There diff
works ok, but blaming is painfully slow without textconv cache, and with
textconv cache, blame says lots of lines are 'Not Yet Committed' which
is wrong.
Here is a test that demonstrates the problem.

It is unfortunate to have to issue thousands of one-byte read calls to
work around dd's refusal to buffer input that would fill a block after
a short read (a3a6f4, 2010-12-13). We could do better by using
"head -c", if it were available on all platforms we cared about.
Replace it with some simple perl.
While doing so, restructure 9300.114 to use a subshell instead of a
script. Subshells can inherit functions (like the new head_c) from
the parent shell while external scripts cannot.

This function recently gained the ability to recognize the documented "0"
and "1" values as false/true. However, unlike regular git_config_bool, it
did not treat arbitrary non-zero numbers as true.
While this is undocumented and probably ridiculous for somebody to rely
on, it is safer to behave exactly as git_config_bool would. Because
git_config_maybe_bool can be used to retrofit new non-bool values onto
existing bool options, not behaving in exactly the same way is technically
a regression.

In git-fsck(1), there was a reference to the warning "<tree> has full
pathnames in it". This exact wording has not been used since 2005
(commit f1f0d0889e), when the wording was changed slightly. More
importantly, the description of that warning was useless, and there were
many other similar warning messages which were not document at all.
Since all these warnings are fairly obvious, there is no need for them
to be in the man page.

"Promote" the reflog command out of plumbing, so that we now run
completion for it. After all, it's listed under porcelain (ancillary),
and we do run completion for those commands.
Add basic completion for the three subcommands - show, expire, delete.
Try completing refs for these too.

Currently, only configured diff helpers get the basename of the file
being compared. Tools specified with "git difftool -x" only get the
names of temporary files for the different versions.
Export BASE so that an external tool can read the name from the
environment. Rather than using a third argument, this avoids breaking
existing scripts which may somewhat carelessly be using "$@" rather than
"$1" "$2".
