Midi output from 2.7.9

[Daniel Tonda Castillo]

Hi:

Lilypond 2.7.9 in Fedora Core 4 now produces decent midi output
except that it doesn't assign the instrument patch name in
Staff.midiInstrument.

If I put something like this:

...
  \set Staff.midiInstrument = "acoustic guitar (nylon)" 
...
The output will have a piano patch assigned to it instead of the
guitar.

Anyway, the line-breaks are now working fine. 

Keep up the fine work...
