Subject: git-merge: add support for --commit and --no-squash
X-Git-Tag: v1.5.4-rc0~388^2~1
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=d08af0ad745869a4fe36bc8df4f9804edfb74eb9;p=git.git

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.
