Oops. Sorry, I tested standalone but didn't test the multiplexer.

The point of the change is to make OLDTOY() argument parsing work so
sha256sum and friends could share help text with sha1sum. And it did!

The problem I was trying to solve is that if the base command is
disabled but an OLDTOY() for it is enabled, the base command's option
string was a null pointer. The NEW problem is that the multiplexer
itself has an option string that SHOULD always be a null pointer, and
now isn't.

Gotta get the conditionals right. Hmmm...
