Interesting! I never thought of G8 as between alto and tenor clefs, but
indeed it is.

The consensus seems to be that when I enable C8 in PMX, pitches should be
entered as they will sound. That'll be more work (due to MusiXTeX's
inconsistent treatment of the clef). But maybe I can take advantage of some
of PMX's partwise-transposition machinery, which I put in a while back. So
inside PMX, for any voice with C8 assigned, I would treat it like treble
clef, except (1) replace the clef symbol with treblelowoct, and (2)
transpose all input pitches up an octave before typesetting. I guess I'll
also have to ensure that if MIDI is requested it DOESN'T get transposed up
an octave.

This could take a while.
