Sorry if I had been assuming too much knowledge of Scheme here.  What
I suggested amounts to replacing the above cited lines with

(ly:stencil-add (ly:stencil-aligned-to stencil X RIGHT)
                (ly:stencil-aligned-to (grob-interpret-markup grob text)
                  X RIGHT))

here.  I haven't actually tested it or looked into what the code even
does so this should be taken with a grain of salt, but that's what
I consider likely to be akin to the previous behavior.
