It's not clear that that behaviour is `*undefined*' as you say.  That
is, I can't find anything resembling a specification of the format of
/etc/passwd.  The closest is passwd(5) but that's obviously much much
later than the de facto standard was established.

All other systems have had first match processing for /etc/passwd
since the dawn of time, and we should do too.
