Anything in quotes is a guitar chord e.g.
"A" "Gm" "B7" "Bm7" "D#aug" "Bbdim7"
Guitar chords must use upper case A-G followed by optional # or b, then
the name of a chord type e.g. "m", "aug", "7". abc2midi currently
recognizes the following chord names :
m, 7, m7, maj7, M7, 6, m6, aug, +, aug7, dim, dim7, 9, m9, maj9, M9,
Lower case a-g followed by optional # or b will generate a single note,
the fundamental, only.

See above.

see my comments about '+' below. Also 'o' gets used for diminished

I'm *very* twitchy about using "+" at all, since I've seen it mean
'sharpened' 'added' or 'augmented'
so C+9 could mean C(#9): C E G Bb D# (sharpened 9)
Cadd9: C E G D (added 9)
or Caug9: C E G# Bb D (augmented 9)
