Subject: [PATCH] git-merge: leave sensible reflog message when used as the
 first level UI.

It used to throw potentially multi-line log message at reflog.
Just record the heads that were given to be merged at the command
line and the action.

Revert the removal of the check in "git-update-ref -m" I made earlier
which was only a work-around for this.
