They don't scale obn my system, which is what I'd expect.  Maybe these
faces don't specify the font on some systems, but the principle is
nevertheless valid.

Which means your fixed-pitch and variable-pitch faces don't specify
the size of the font.  But otherwise what I said was correct, and
should be taken into account.
