Rendering Libero's example under 2.7.9 aligns the far left edge of
both indications (ie, the far left edge of the "s" in the ponticello
indication, and the far left edge of the "o" in the ordinario
indcation) with the dead center of the notehead.

My preference would be to center both indications over the notes,
somewhat by analogy to dynamics.

It seems that the pair of ...

 \override TextScript #'self-alignment-X = #center
 \override TextScript #'X-offset-callbacks =
#`(,Self_alignment_interface::aligned_on_self)

... should do the trick, but I can't make the indications budge at
all, unfortunately. Perhaps the overrides must be somehow *local* to
the pair of strings assigned to #edge-text, but I don't know the
syntax for sticking in the overrides locally.

Maybe Graham or Mats or Nicolas can explain how to adjust the x-axis
alignment of edge text independently?
