Even if you use my modified version (which hopefully is not so
inelegant), the comment about toupper('\0') still applies.
My reading of `man toupper(3)` is that if c is neither lowercase or
uppercase it is returned as-is. As long as it's unsigned char, which
'\0' is.
So I think the behavior is indeed defined.
