Both patches does the same thing.

The only difference is that my patch parses arguments using a while loop
(and shifts the first argument), while the patch from Erik parses
argument using a for loop.

Here is a diff of both patches.

	++: Erik

My patch is using a while --^ (+ shift)
	++for arg in "$@"
	++do
	++	case "${arg}" in
Erik's solution uses a for -^

Erik's forgot to indent the esac.

Otherwise, only the `-+ shift' would have been present is that chunk [*].
