After some more digging, I found the following in lib/auth_unix.c,
if (!sawalpha) return NULL; /* has to be one alpha char */
Certainly looks like the "bug" isn't there by mistake. :-) It is
tempting to simply comment out that check. On the other hand, I assume
there's a reason for that check to be there.
But what that reason is I don't know. Could anyone enlighten me?
