The CVS documentation mentions the old usage; look for "older systems".

"tail --help" (and therefore the man page) does not mention this,
because it is supposed to be brief.  A discussion about obsolete usage
would have to be longwinded to be accurate and would probably cause
more harm and confusion than it'd cure.
