problem with horizontal shift of note

[Tom Cloyd]

After 3 months away from Lilypond, I'm back, thankfully. All updated and 
sailing...right into a wall. I could really use a hint about this 
current problem.

I cannot get a horizontal shift of a note, resulting in an ugly 
collision. I think the problem is the "too many clashing note columns" 
warnings I keep getting. I dimly recall someone telling me what to do 
with that, but it's long gone from my memory, and in any case hasn't 
been a problem (that I'm aware of). My score is, and has been, working 
well. This is an old problem I'm trying to fix tonight.

At the risk of overload, I'll include the full program and CLI output, 
the latter first:
