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
