9ca8f6079c "git-merge": allow fast-forwarding in a stat-dirty tree
We used to refresh the index to clear stat-dirtyness before a fast-forward
merge.  Recent C rewrite forgot to do this.

74f5b7fba4 builtin-merge.c: Fix option parsing
Now "git merge -m" needs a message, and errors out with the usage
text if none is given.
This way, t7600-merge.sh is fixed.

01941bd543 t7600-merge: Use test_expect_failure to test option parsing
It used plain 'if git merge ...', which hides a segfault. The test does not pass.

711f6b295c reduce_heads(): protect from duplicate input
Because we do not try computing merge base with itself for obvious
reasons, the code was not prepared for an arguably insane case of
the caller feeding the same commit twice to it.

Noticed and test written by Sverre Hvammen Johansen

3d1dd4728b reduce_heads(): thinkofix
When comparing two commit objects for equality, it is sufficient to
compare their in-core pointers because the object layer guarantees the
uniqueness.  However, comparing pointers to two "struct commit_list"
instances that point at the same commit does not make any sense.

Spotted by Sverre Hvammen Johansen who wrote an additional test to expose
the problem, fixed by Miklos Vajna.

d492b31caf t/: Use "test_must_fail git" instead of "! git"
This patch changes every occurrence of "! git" -- with the meaning
that a git call has to gracefully fail -- into "test_must_fail git".

This is useful to

 - make sure the test does not fail because of a signal,
   e.g. SIGSEGV, and

 - advertise the use of "test_must_fail" for new tests.

d8abe148be merge, pull: introduce '--(no-)stat' option
This option has the same effect as '--(no-)summary' (i.e. whether to
show a diffsat at the end of the merge or not), and it is consistent
with the '--stat' option of other git commands.

Documentation, tests, and bash completion are updaed accordingly, and the
old --summary option is marked as being deprected.

82ebb0b6ec add test_cmp function for test scripts
Many scripts compare actual and expected output using
"diff -u". This is nicer than "cmp" because the output shows
how the two differ. However, not all versions of diff
understand -u, leading to unnecessary test failure.

This adds a test_cmp function to the test scripts and
switches all "diff -u" invocations to use it. The function
uses the contents of "$GIT_TEST_CMP" to compare its
arguments; the default is "diff -u".

On systems with a less-capable diff, you can do:

  GIT_TEST_CMP=cmp make test

b4ce54fc61 remove use of "tail -n 1" and "tail -1"
The "-n" syntax is not supported by System V versions of
tail (which prefer "tail -1"). Unfortunately "tail -1" is
not actually POSIX.  We had some of both forms in our
scripts.

Since neither form works everywhere, this patch replaces
both with the equivalent sed invocation:

  sed -ne '$p'

aadbe44f88 grep portability fix: don't use "-e" or "-q"
System V versions of grep (such as Solaris /usr/bin/grep)
don't understand either of these options. git's usage of
"grep -e pattern" fell into one of two categories:

 1. equivalent to "grep pattern". -e is only useful here if
    the pattern begins with a "-", but all of the patterns
    are hardcoded and do not begin with a dash.

 2. stripping comments and blank lines with

      grep -v -e "^$" -e "^#"

    We can fortunately do this in the affirmative as

      grep '^[^#]'

Uses of "-q" can be replaced with redirection to /dev/null.
In many tests, however, "grep -q" is used as "if this string
is in the expected output, we are OK". In this case, it is
fine to just remove the "-q" entirely; it simply makes the
"verbose" mode of the test slightly more verbose.

e6d1f76ccf git-merge.sh: better handling of combined --squash,--no-ff,--no-commit options
git-merge used to use either the --squash,--no-squash, --no-ff,--ff,
--no-commit,--commit option, whichever came last in the command line.
This lead to some un-intuitive behavior, having

 git merge --no-commit --no-ff <branch>

actually commit the merge.  Now git-merge respects --no-commit together
with --no-ff, as well as other combinations of the options.  However,
this broke a selftest in t/t7600-merge.sh which expected to have --no-ff
completely override the --squash option, so that

 git merge --squash --no-ff <branch>

fast-forwards, and makes a merge commit; combining --squash with --no-ff
doesn't really make sense though, and is now refused by git-merge.  The
test is adapted to test --no-ff without the preceding --squash, and
another test is added to make sure the --squash --no-ff combination is
refused.

The unexpected behavior was reported by John Goerzen through
 http://bing.sdebian.org/468568

d08af0ad74 git-merge: add support for --commit and --no-squash
These options can be used to override --no-commit and --squash, which is
needed since --no-commit and --squash now can be specified as default merge
options in $GIT_DIR/config.

The change also introduces slightly different behavior for --no-commit:
when specified, it explicitly overrides --squash. Earlier,
'git merge --squash --no-commit' would result in a squashed merge (i.e. no
$GIT_DIR/MERGE_HEAD was created) but with this patch the command will
behave as if --squash hadn't been specified.

aec7b362ad git-merge: add support for branch.<name>.mergeoptions
This enables per branch configuration of merge options. Currently, the most
useful options to specify per branch are --squash, --summary/--no-summary
and possibly --strategy, but all options are supported.

Note: Options containing whitespace will _not_ be handled correctly. Luckily,
the only option which can include whitespace is --message and it doesn't
make much sense to give that option a default value.
