Thanks.  Looking more closely at the results, \markup centers the left
edge of the circle over the center of the note.  Plain latex puts the
left edge of the circle over the left edge of the note, so there is a
small difference.  \center-align with \markup, puts the right edge of
the circle over the center of the note(!), which is often a quite
tolerable situation.  Plain latex with backspaces can center the circle
quite well, and hspace can tweak it too, but I didn't test that.  There
is a problem with circling two letters, as (La).  I don't know
whether anyone wants to do that.  daveA
