rewind: alias the command to undo

This is a step in unifiying rewind and undo and not talk about them as different
commands or concepts. If there exists rewind command, that should be an alias of
undo and the vice versa.

The exact implmentation detail and how the command works etc. is a different
thing but there should be just one command.
