Surprisingly (it's undocumented) but the exact same synopsis seems
to work here with "cvs diff":

$ ident Makefile.inc1
Makefile.inc1:
     $FreeBSD: src/Makefile.inc1,v 1.418 2004/03/18 10:17:03 ru Exp $
$ cat CVS/Tag
cat: CVS/Tag: No such file or directory
$ cvs di -jRELENG_4:2002/01/01 -jRELENG_4:2003/01/01 --brief Makefile.inc1
Index: Makefile.inc1
===================================================================
RCS file: /home/ncvs/src/Makefile.inc1,v
retrieving revision 1.141.2.39
retrieving revision 1.141.2.57
diff -u -p --brief -r1.141.2.39 -r1.141.2.57
Files /home/ru/tmp/cvsv60oN8 and /home/ru/tmp/cvsmonEXm differ
