commit: add amend mode for commit -i
When I moved crecord into core, I didn't include the toggleAmend function (to
switch from commit to amend mode). I did it because it would have made it more
difficult to use record and crecord interchangably. This patch reintroduces the
amend mode for commit -i as well as two tests to verify the behavior of the
function.
