problem with beam collision (was: problem with cross-staff stems, on lilypond-user)

[Janek Warchoł]

Hi David,

glad it worked :)
The change is almost certainly due to new beam collision algorithm.
I'm forwarding this message to the development team so that they will
know about this issue.
I'm not sure if it's a bug, though - Phil, you are the bugmaster, can
you give us your opinion? :)

cheers,
Janek
