Re: [RFC/PATCH] rebase--interactive: Add "sign" command

Chris Packham [off-list ref] writes:

This is similar to the existing "reword" command in that it can be used
to update the commit message the difference is that the editor presented
to the user for the commit. It provides a useful shorthand for "exec git
commit --amend --no-edit -s"

Hmm, what should those who want to amend and sign do, though?
