i've found the issue and applied a fix that works some of the
time. the difficulty is that you can have a :| |2 sequence
which isn't catered for in try_parse_bar()

it would be nice if it supported the [1, [2 abc repeat syntax too.

i found a fix for this too. probably the same one.

it's necessary unless abc2ly does entirely manual beaming.
i can see arguments for and against doing this.
for: all beaming is manual in abc already
against: lilypond does an excellent job on its own,
and the resulting files would be more verbose.

i'd be happy to see a command-line flag to turn on manual beaming,
but it's not a trivial change to abc2ly, AFAICS.
