On 5/19 Bob privately sent me proposed changes for pmx.tex to go with the
new definition of \centerbar. Without going into the detailed coding, I'll
report that limited comparisons of horizontal positioning between the
current and proposed coding are mixed: in-staff full-bar pauses,
single-symbol multibar rests, and raised full-bar half-rests stay the same
(and centered); raised pauses are currently a bit off center and got worse;
in-staff full-bar half rests are currently off-center and got better;
multi-symbol multi-bar rests by eyeball appear to remain centered but become
slightly more spread out. These mods would affect only pmx.tex but not the
PMX code.

There are still possibly other PMX constructs that would be affected; one
that comes to mind that I haven't checked is vertically stacked pairs of
rests in multivoice staves, and there may be others I haven't thought of. 

Considering the possible foreseen and unforeseen domino effects of the
proposed change in \centerbar at this time, both with PMX and pure MusiXTeX,
I would urge extreme caution before implementing it. Could an alternate
approach simply be to use a different name (say \Centerbar) for the new
macro, leave \centerbar as is, and modify the manual to explain the
differences?
