This is the regression test for issue 176.
It uses 'strict-note-spacing, so the collision is allowed :
"When strict-note-spacing is set, notes are spaced without regard for  
clefs, bar lines, and grace notes,"

It was added when single-line scores were right-justified, stretching the  
notes very widely, so the overlap was not seen originally.

The test also causes 'programming errors' to be printed, but these are also  
allowed; see last few comments on issue 176.

I suggest that the resolution of this issue would be to make the texidoc  
explain the condition for passing the test.  I tried do to so but could not  
understand the original problem.  If no-one can, a second resolution could  
be to remove this test.
