extenders over bar lines in 2.19.55 [was: Automatic Lyric Extenders]

[Alexander Kobel]

[Bug report summary:]

Extenders are not drawn anymore for melismata that include notes that 
are not bar-aligned, starting somewhere between 2.19.50 and 2.19.55. 
M(N)WE attached - the first and second score should have extenders until 
the last note.

great that you found the snippet useful. Please note that this is a 
"workaround" that happens to do a (surprisingly) good job. A proper, 
more mature integration of automatic extenders is in the works, but 
after initial enthusiasm, it turned to be a bit more invasive than 
expected. I hope that there will be some news on that front "soon".

However, this problem seems unrelated (as you remark, it's completely 
independent of automatic extenders) and 2.19.55-ish, hence I cross-post 
to bug-lilypond:
Extenders seem not to be drawn anymore for melismata that include notes 
that are not bar-aligned. Note that in your original example, already 
the first note is longer than measure 1; that seems to be the culprit. 
Attached is a more detailed example.

Did you, by chance, spot the problem already on earlier dev releases? I 
did not see it on 2.19.50 (which I just uninstalled, unfortunately), and 
I don't have intermediate versions available right now.


Cheers,
Alexander
