Allow editing of a revert-message

I think all commit operations should allow editing of the message (ie we
should do this for merges too), but that's _particularly_ true of doing a
"git revert".

We should always explain why we needed to revert something.

This patch adds a "-e" or "--edit" flag to "git revert", although I
actually suspect it should be on by default (and we should have a
"--no-edit" flag to disable it, probably together with an automatic
disable if stdin isn't a terminal).
