"If it wasn't <this>, we know it was <that>" really implies that <this> and
<that> are values possible for the same expression, doesn't it? How could
a pointer (NULL) and a character ('/') possibly be such?

Could you explain the meaning of thus "fixed" comment? I'm not even asking
to explain why it is correct that way, just what the hell is it supposed to
mean?

NAK, in case it's not obvious from the above...
