[PATCH] rebase: new option to post edit a squashed or fixed up commit

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

After squashing or fixing up, you may want to have a final look at the
commit, edit some more if needed or even do some testing. --postedit
enables that. This is (to me) a paranoid mode so either I enable it
for all squashes and fixups, or none. Hence a new option, not new todo
commands that give finer selection.
