No, it doesn't.

Also, I don't get the same behavior that you do, with grep 2.5.1.
For example:

   $ cat /etc/motd
   Sun Microsystems Inc.   SunOS 5.10      Generic January 2005
   $ cat p
   a
   b
   $ grep -v -f p /etc/motd
   $ grep -f p /etc/motd
   Sun Microsystems Inc.   SunOS 5.10      Generic January 2005
   $ 

Perhaps the problem depends on your installation somehow.
