New issue 2441 by address@hidden: Stems no longer adjust for merged  
note heads

The up-stem is disconnected from the triangle-shaped note-head, ever since
 commit 32570e8ac85561afc1f59712301ee80c0d69d2b3
 Better pure height approximations for stems.

There is code in note-collision.cc to adjust the up-stem to meet the merged  
note-head, which is lower than the note-head would be if it were not  
merged.  After re-arrangement of the stem code, that adjustment has no  
effect on the printed stem.

The regression test, ‘collision-head-solfa-fa.ly’ did not reveal the change  
because it uses quarter notes, and the problem appears only with flags or  
beams.
