xgettext: parse arguments correctly

`*) break` will stop parsing immediately after the first argument is
parsed, leaving all other arguments ignored.

To prevent shifting arguments more than we have, we should check if
there's any argument left. Otherwise, script will exit with `can not
shift anymore`.
