I'm not surprised the positioning is off.  I have not done any positioning
work.  They're just displayed with \markup { \musicglyph
#"scripts.accordion.push"}.  After all, I signed up for the job of
developing push and pull symbols that would be "nicely integrating with the
normal Lilypond fonts (and not confusing with other accents or marks)".

The job of "creating the magic needed for placing them well in connection
with other articulations/fingerings" is still unclaimed.

I think that the engraver will need to move stuff around to align with the
note column.  It should be able to do that quite easily.
