Nope.  No modifications. Except expanding the usage message to include the
-l option.

Nope.  The man page for crontab, while not a verbatim copy of the V.2.1
man page uses the same language:

	Crontab copies the specified file, or standard input if no
	file is specified, into a directory that holds all user
	crontab files.

This isn't the clearest and most complete description of crontab's behavior
but I don't see the "append" implication either.
