rcs tags and tests

Hi,

I am having troubles with the regression tests, because I get false negatives
in case there was, in the original file a tag like:

$Id: texinfo.txi,v 1.219 2002/03/28 16:36:00 karl Exp $

When I commited to cvs it became

$Id: texinfo.txi,v 1.1 2003/02/03 16:10:29 pertusus Exp $

What could I do to avoid that kind of wrong behaviour ?

Pat

Note: the $Id: texinfo.txi,v 1.219 2002/03/28 16:36:00 karl Exp $ comes from
the texinfo manual. From an example if I recall well.
