How about adapting abc2midi's %%MIDI transpose function. Just allow it
to be included in the V: field like this:
V:1 MidiTranspose -3
or something like that.

I think we should treat transposition and intonation as separate issues
in any case. Besides, the intonation function is a bit dangerous to use
in midi playback in any case. It uses the midi pitch bend function and
that isn't standardized. It works well in BarFly, which always use
QuickTime for Midi playback, but a general ABC player that might use any
synth software/hardware to produce the sound might get into serious trouble.
