Fix: tested that p is in the range 0 to 7.

abcmidi: The instrument=<note1>/<note2> is defined as a shorthand
for score=<note1><note2> sound=c<note2>. For instrument=,<note1>
indicates the key of the instrument and <note2> is either c or C.
The sound= directive specifies the note and how it is played.
For example, sound=c_B indicates that the note c is played as
_B on the instrument. Every note is transposed down by two semitones.
The problem is that, the notes in the instrument directive are
in the opposite order of the sound= and score= directives.
The function parsesound() in parseabc.c treats takes care of
the directives sound =, shift = and instrument =.
Unfortunately, all these directives are treated in the same
manner causing the instrument= directive to transpose
in the wrong direction.
Fix: for the special case, instrument=, transpose is set to
p1 - p2 instead of p2 - p1.
The '/' is only part of the instrument= syntax. Note2midi has
an extra parameter, word, indicating the type of directive.
It will issue a warning if it detects a '/' in the sound= or
shift= directives.
