New issue 2848 by address@hidden: abc2ly produces very out-of-date  
output
http://code.google.com/p/lilypond/issues/detail?id=2848

With some abc code from a colleague (without all the headers and stuff):

z3([DF]-D^D)|[^DF](E [EA])[DF][EG]G|[F2B2][D2F2][B,D]E|

we get this lilypond code:

r4. <<   d'8 (   fis'8   >>  ~    d'8    dis'8  -) \bar "|" <<   dis'8
fis'8   >> e'8 ( <<   e'8    a'8  \spanrequest \stop "slur" >> <<   dis'8
fis'8   >> <<   e'8    g'8   >> g'8  \bar "|" <<   fis'4    b'4   >> <<    
d'4
 fis'4   >> <<   b8    d'8   >> e'8  \bar "|"

Wah.  Where did all those << and >> come from - they're chords.  And what  
about the \spanrequest - I had to go back to 1.6 to find that documented.   
convert-ly _might_ fix it up - I've not tried - but the script now should  
not be generating such odd code.

And if you delete the | from the end of the line, abc2ly crashes.

I'm entering this because I _may_ look at updating it if I can. Also  
marking it as frog because it's not too hard, IMHO
