Hmm. Thanks. Sorry about the patch glitch. (On my Ubuntu system,
patch has a -R flag that would seem to take care of that ...)
I accepted Kurt's explanation. I'm curious what the protocol is when
R-core members differ? (I would have guessed that conservatism would
rule, or the opinion of the original author of the functions (I don't
know who contributed Reduce et al.), but perhaps Kurt doesn't have
strong feelings about this ...
