[PATCH v3 3/6] rebase -i: add short command-name in --autosquash

[Liam Beguin <liambeguin@gmail.com>]

teach `git rebase -i` to recognise short command-names when using the
'--autosquash' option. This allows commit with titles beginning with
"s! ..." and "f! ..." to be treated the same way as "squash! ..." and
"fixup! ..." respectively.
