Maybe, but it already says you should set the variable in two different
places.

I definitely meant --unset.  If the user knows the distinction, and
wants to return the variable to the state it had before his test
(perhaps so that a future --global setting might take effect), he would
use this sequence.  He might then be somewhat surprised to see that
rerere is now permamently enabled for this repo.

Probably I'm worrying too much about a weird fringe case though.
