[PATCH] git-merge: make it usable as the first class UI again.

[Junio C Hamano <junkio@cox.net>]

reflog wants to have a short-and-sweet single line message, but
its set_reflog_action was slurping the whole command line arguments.
When given a multi-line commit message from the command line, reflog
code refused to update the ref with the resulting commit.

 * When pull threw huge merge message, it has already set the
   reflog action on its own so this breakage was hidden.  Also
   because most of the time people did not specify -m message
   (or use the old-style <msg> HEAD <others>) from the command
   line, nobody seems to have noticed this.
