amend: allow the --logfile argument to work properly
Though documented to work, using --logfile previously set the message option to
that of the parent commit, and cause amend to abort with this message:
abort: options --message and --logfile are mutually exclusive
It's not clear why the 'edit' option is popped, but this option is only fetched
in order to let the core commit command do the work.
