Attached patch should fix this one and theoretically even *speed up* glyph 
name lookup, since it removes obsolete scheme code.  Instead of trying to 
fix the scheme code, I added a new longa note head to the feta font.  It 
looks exactly like a brevis head, but with a stem like quarter note. 
Maximae are not handled by this patch, but I actually have not ever seen a 
Maxima in modern font, so this is a generally open issue to be handled 
separately.

May I apply this patch?
