Subject: git-merge: warn when -m provided on a fast forward
X-Git-Tag: v1.5.0.4~8
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=be242d576c4457bec1cb748b144eb287e98ac0b5;p=git.git

git-merge: warn when -m provided on a fast forward

Warn the user that the "-m" option is ignored in the case of a fast
forward.  That may save some confusion in the case where the user
doesn't know about fast forwards yet and may not realize that the
behavior here is intentional.
