[PATCH] commit: don't start editor if empty message is given with -m

From
René Scharfe <rene.scharfe@lsrfire.ath.cx>

Message-ID

If an empty message is specified with the option -m of git commit then the editor is started. That's unexpected and unnecessary. Instead of using the length of the message string for checking if the user specified one, directly remember if the option -m was given.
