commit: if relevant, tell user their commit message was saved.
(issue1635)

Specifically, if:
  1) the user edited the message (it didn't come straight from -m) and
  2) the commit was aborted by an exception
then the saved commit message in .hg/last-message.txt could come in handy, so
mention it with a ui.write().

This doesn't help users who manually rollback to amend a changeset:
the fact that the message was saved to .hg/last-message.txt is
invisible in that case.
