abc2midi: gchord bug
The following example produces some strange artefacts on starting
the midi file for some players.

%%MIDI gchord GHIc
K:C
GAB | "C"c4 C4 |
Explanation: the output midi file plays a note with midi pitch 0
in the accompaniment channel. The problem originates in the dogchords()
function for switch case 'G': in genmidi.c. Since g_started is 0,
the second branch of the if statement is executed, but the pitch
value in gchordnotes[gchordnotes_size] contains 0.
Fix: the switch statement should not be executed since g_started is
0 (i.e. the gchord accompaniment does not start till "C" is encountered).
The switch statement is now bypassed when either g_started
or gchords is 0. The tests for gchords and g_started in all the
case statements were removed since they are unnecessary.
