passwd{1} doesn't match the program. notably, the args documented are not those used by the program. i hate your bugs as much as i hate microsoft bugs...more, in fact...i don't see so many bugs in microsfotware...
the "i hate your bugs" was overly mean and ungenerous...sorry, but i've paid more to redhat than i've paid to microsoft and, well, ... this isn't bug report stuff.
Thiswill be fixed in passwd-0.64 (or later) in Raw Hide.
