Good !  I've put in the patch, and, at the same time split out all
ancient entries into a separate font: tex fonts (and PS fonts as well)
can only have 256 glyphs. Almost half of the feta font was taken up by
the various ancient glyphs.

This means that all ancient notation files will be broken by the next
release. I'm not sure what the proper solution is for allocating the
glyphs. Maybe there should be separate font file for every "edition"
(i.e. feta-hufnagel, feta-medica, etc.), so you can do

   \property Voice. NoteHead  #'font-family = #'feta-hufnagel

to set ancient notation. This approach would also get rid of a lot of
conditional code for setting the glyph style. For now, the ancient
font is called parmesan.

In the passing I also noticed that two the noticeably rounded
characters (leger line and sharp) use bigger values for blotting
stroke (1.3 and 2.0 blot_diameter respectively). Since I like those
characters, probably one thing we should try is increasing
blot_diameter.
