rollback: clarifies the message about the reverted state (issue2628)
Previously, when rolling back a transaction, some users could be confused
between the level to which the store is rolled back, and the new parents
of the working directory.
$ hg rollback
rolling back to revision 4 (undo commit)
With this change:
$ hg rollback
repository tip rolled back to tip revision 4 (undo commit)
working directory now based on revision 2 and 1
So now the user can realize that the store has been rolled back to an older
tip, but also that the working directory may not on the tip (here we are
rolling back the merge of the heads 2 and 1)

$ cd t

rollback by pretxncommit saves commit message (issue 1635)
$ echo a >> a
$ hg --config hooks.pretxncommit=false commit -m"precious commit message"
transaction abort!
rollback completed
abort: pretxncommit hook exited with status * (glob)

.hg/last-message.txt:
$ cat .hg/last-message.txt ; echo
precious commit message
same thing, but run $EDITOR
$ cat > editor << '__EOF__'
> #!/bin/sh
> echo "another precious commit message" > "$1"
> __EOF__
$ chmod +x editor
$ HGEDITOR="'`pwd`'"/editor hg --config hooks.pretxncommit=false commit 2>&1
transaction abort!
