Well, AFAIThink the semantics do not change -- just extends a bit, and
thus allow to be extensively checked for example by FreeBSD-styled CVSROOT
scripts like commit_prep.pl
BTW, I've written a little patch to CVS similar to peter's patches: it adds
idexpmode options to CVSROOT/options -- attached just in case anyone
interested.

#-DSC-# idexpmode option for CVS
This patch adds new option for cvs. You can specify idexpmode=<MODE>
in CVSROOT/options admin file to select $ Id $ RCS keyword expansion mode.
MODE may be on of the following:
Id last path component; default
Header full path including repository root
CVSHeader path relative to repository root
