It's not a composite, either. And there are already many cases where you have to say "let p be an _odd_ prime" because the statement fails for p=2, so many that maybe allowing 1 in (and having to explain it away in many more theorems) is not much worse that having it in a special weird category of its own. It's just terminology. -- Please don't Cc: me privately on mailing lists and Usenet, if you also post the followup to the list or newsgroup.
