(I hope I didn't send accidentally an empty reply. Sorry about that.)

Merging explicitly works nicely (tried in 'example.ly').

Instead, I found an other bug in beaming with lilypond 1.5.6.

In 'example.ly' is shown that when switching between staffs, a flag is
missing from a note which has manual beaming. Below is an ASCII-example in
the case the problem do not show in other versions. Both notes should have
the same 1/8-duration.
