[PATCH/RFC 07/20] rebase: stricter check on arguments

[Martin von Zweigbergk <martin.von.zweigbergk@gmail.com>]

To align git-rebase.sh better with git-rebase--interactive.sh, be
stricter about checking that, when used, '--continue', '--skip' and
'--abort' is the only argument.

Since $strategy and $verbose are currently saved only by interactive
rebase, checking that they are not passed on the command line would
break any existing uses of 'git rebase --strategy=<x> --continue'.
Instead, relax the check and let the options be ignored by interactive
rebase once refactored (the relaxation will not be effective until
further refactoring, however).
