a = re.sub ( '-', '- ', a) # split words with -
+ a = re.sub ( ' - - ', ' -- ', a) # unless was originally " -- "
Just being curious:
Maybe I am totally wrong (since I do not know the abc format in detail),
but shouldn't this be rather something like
a = re.sub ( '([^-])-([^-])', '\\1- \\2', a) # split words with "-" unless was
originally "--"
or similar (untested)?
Greetings,
Juergen
