Re: [PATCH] Have git-revert, git-cherry-pick cleanup ./.msg upon successful completion.

What about this change instead?  We make cherry-pick/revert
use the same temporary file as merge, which is under .git/
(something Alex mentioned he wanted).  I think the use of ".msg"
in cherry-pick/revert has always just been a bug, and not a feature,
so I'm really not against changing things around like this.

While I would not say this is not an improvement, this makes
MERGE_MSG even less about merges and pushes us away from a
sensible "git whatnow".
