This may pose a problem for some software which attempts to render the
midi file in music notation.

James Allwright has made significant improvements to parseabc.c, toabc.c,
and yapstree.c related to repeat checking. In parseabc.c, new functions
were introduced: init_voice_contexts, reset_parser_status,
interpret_voice_label, check_bar_repeats, and check_and_call_bar().
The functions isnumberp(), init_voicecode(), and interpret_voicestring()
have been retired. Reset_parser_status() is called each time a new
X: reference field command is encountered. Check_bar_repeats() replaces
a lot of the code that appears in event_bar() defined in toabc.c and
yapstree.c. parsemusic() calls event_bar indirectly through the
function check_and_call_bar(). Minor changes were made to toabc.c, store.c
and yapstree.c to accommodate the changes to parseabc. In particular,
a new flag repcheck is introduced and connected to parseabc.c as
an extern (in parseabc.h). In addition a new struct (voice_context)
has been introduced in parseabc.h.
