Cross-staff beam craziness (when down-markup combines with down-articulation)

[Trevor Bača]

Hi,

Crossposted as Google #430.

This one was really, really nasty to find.

In the following snippet we need the whole witches' brew of settings to
cause the bug (but it's quite repeatable). Specifically, the combination of
BOTH the down-markup AND the down-articulation TOGETHER WITH the
staff-changing note causes stemming and beaming to completely screw up.

Commenting out EITHER the down-markup OR the down-articulation OR BOTH
causes the stemming and beaming to work perfectly.

Bug shows up in both .29 and .30 but I haven't tested earlier builds to see
when exactly it entered.


%%% BEGIN %%%

\version "2.11.30"

\new PianoStaff <<
   \new Staff = RH {
      \time 1/4
      c''16 [
      c''16
      \change Staff = LH
      c''16 \tenuto _ \markup { foo }
      \change Staff = RH
      c''16 ]
   }
   \new Staff = LH {
      s4
   }
>>

%%% END %%%


Really nasty is some heavily \markup-ed piano music.
