commit: save commit message so it's not destroyed by rollback.
(issue1635)

Rationale: if a pretxncommit hook rejects this commit, the transaction
is rolled back and the user's commit message is irrevocably lost.
So save a copy in .hg/last-message.txt, just in case.  Also handy if
the user deliberately rolls back a commit in order to amend it.
