These are the command line option equivalents of the 'merge.log' config
variable.
The patch also updates documentation and bash completion accordingly, and
adds a test.

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.

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

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'

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.

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

Using \+ to mean "one or more" in grep without -E is a GNU
extension outside POSIX. Avoid it.

These new options can be used to control the policy for fast-forward
merges: --ff allows it (this is the default) while --no-ff will create
a merge commit.

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.

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.

This test-script excercises the porcelainish aspects of git-merge, and
does it thoroughly enough to detect a small bug already noticed by Junio:
squashing an octopus generates a faulty .git/SQUASH_MSG.
