no warning on open of cvs controlled file

[Harry Putnam]

Until recently, whenever I opened a symlink to a file controlled by
cvs, I would get prompted about the fact that it was a cvs file.

That no no longer happens.  I don't remember setting anything to stop
that behavior and a grep on `cvs'  .emacs /path/site-start.el
doesn't show any hits.

Any clues what might cause this?

Grepping grep  cvs /usr/local/emacs/21*/etc/NEWS

Gets a few hits but none look like they might be about changing
that behavior.
