Subject: commit: use value of GIT_REFLOG_ACTION env variable as reflog message
X-Git-Tag: v1.7.2-rc0~20^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=643cb5f7c99e77a4a3e97213dd226a7dc2650c02;p=git.git

commit: use value of GIT_REFLOG_ACTION env variable as reflog message

The environment variable GIT_REFLOG_ACTION was used by git-commit.sh,
but when it was converted to a builtin
(f5bbc3225c4b073a7ff3218164a0c820299bc9c6, Port git commit to C,
Nov 8 2007) this was lost.

Let's use it again as it is more user friendly when reverting or
cherry-picking to see "revert" or "cherry-pick" in the reflog rather
than to just see "commit".
