[cvsnt] Suppress blank login warning

[Glen Starrett]

Tony -- Is there a reason that -q and -Q don't suppress the "cvs 
checkout: Empty password used - try 'cvs login' with a real password" 
message when using an anonymous login?  The cvshome.org CVS doesn't 
complain at all with a blank password.

The reason I ask is because I'm writing a script for use with CRON 
that'll complain on every execution unless I manually login to the URL 
beforehand or add a .cvs/cvspass entry.  If that is necessary, does *nix 
CVSNT honor the CVS_PASSFILE environment variable, or is it always 
.cvs/cvspass?  I have the script setting it, but I just figured out the 
format is slightly different from the cvshome.org version.

Regards,
