I do the subtraction in my head, but an awk script would easily be able
to do some simple field splitting before it does the arithmetic to find
the previous revision number.

No need to invoke the bulk and overhead of perl for such a trivial bit
of string manipulation and arithmetic! ;-)
cvs diff -r $(cvs status file.c | awk '$1 == "Working" {print $3}') file.c
I'll leave the matter of doing the field splitting and arithmetic as an
"exercise for the reader".... :-)
