Much faster than I expected to see it after throwing the suggestion into
the long neglected bug report - thanks again.

Since there were enough callers in the old world to make an 
XmuClientWindow useful, does that suggest this should become
a shared utility function in something like xcb-util?

While some might like to see configure have an --enable-xcb option and
#ifdefs between the old and new code, I think it would be just as 
acceptable to use git branches to choose between libX11 & libxcb - make
a xlsclients-1.0-branch for people who need to continue using the libX11
code (who can continue making new 1.0.x releases of it until they're
ready to switch) and then make xcb-only code become xlsclients 1.1 or
