rebase: act on command line outside parsing loop
To later be able to use the command line processing in git-rebase.sh for both interactive and non-interactive rebases, move anything that is specific to non-interactive rebase outside of the parsing loop. Keep only parsing and validation of command line options in the loop. Signed-off-by: Martin von Zweigbergk <martin.von.zweigbergk@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
