You directed someone recently to the page which accesses the search
of the archives, and the engine searched a phrase, not just a word.
It's excellent.

This works for some reason, with one line in the markup:

cs'4^\markup{\center-align <\italic \bold "8va - - - - - "> }

and \box does indeed box whatever you have without moving it to
the right.  Maybe that has something to do with \box being
able to use the bounding box of the letter without running into
others?

I can see now why it's harder to do than \box.  At least the rings can
be made and centered pretty well anyway, so it's not critical.  daveA
