Potential fix offered - changes via slight horizontal shift.

Unfortunately, the horizontal shift to the left obscures the intent of simultaneous notes.  Simultaneous noteheads are usually placed as closely as possible.

I think the desired output is either (1) a longer stem, or (2) moving the g64 to the right as if it were dotted (g64.).

Mike has started over with a new patch to lengthen the stem, and we are working on making it lengthen in the correct situations.

Mike, was your patch in comment 3 a serious one?  I'm not certain where we stand on this particular issue... I suspect that various other changes (especially Keith's work on 1472) may change this.  And you're doing fantastic work on issue 37 right now, so I don't want to distract you by getting back into this issue.

I'm going to mark the patch "needs work" for now, and when other stuff settles down, you can either revise the patch, or just put it on codereview.

Shouldn't shortening the flag be the desired solution? As we're going to have plenty of shortened flags available, this may be the most elegant one.

Connor Harris has produced another example of colliding flags and noteheads:

\relative c''{
  << { c4 b a2 } \\ { g'4 f8\noBeam f e2 }  >> \noBreak
  << c64 \\ c1 >>
}

here is another quite frequent flag notehead collision:

\relative c' { <g' a>8 }
