I've been looking at the problem Bernhard discovered but I don't have a
solution yet. It seems to appear when a double-whole-note rest is raised or
lowered. The same problem is generated by the much simpler file
======================
1 1 8 2 8 2 0 0 1 1 20 0

t
./
g94 r9+2 /
======================

In pmx.tex I redefined \liftpause and defined \liftPAuse (it's not in
musixtex.tex !?) so that they would act as spacing commands. (Can anyone
explain why MusixTeX's definition of \liftpause is NOT a spacing command,
while \pause is !???). Anyhow, something in my \liftPAuse macro is not
working like it should. Any MusixTeXperts are welcome to jump in here and
supply alternate macros for \liftpause and \liftPAuse that provide raised,
properly spaced rest symbols. By proper spacing, I mean that that the macro
should move the pointer horizontally by one \noteskip from the starting
point at the left-hand edge of the character, just like any well-behaved
note or rest macro.

For me, there are spacing errors, i.e., [ ] [ ] etc, at this point. There
will never be such errors on the first pass because PMX sets \elemskip to a
very small value at that point.

Not for me.

I'm sure those blanks don't cause any problem.
