printf("%s", (void*) NULL) is UB, so doesn't need testing. Thanks @chux.

Yes, that is UB, so doesn't need a test case. I confess I was thinking ahead to an implementation of %p - it's useful to have a distinct representation for null pointers there. I'll remove that recommendation.

"Test cases ... null pointers with the %s specifier": Hmmm. As printf("%s", (void*) NULL) is UB, testing myprintf() would seem optional, though perhaps informative, as any result would match UB.
