lily/line-spanner.cc:113: Grob *acc = Note_column::accidentals
(bound_grob->get_parent (X_AXIS));
acc is an AccidentalPlacement, so should be renamed to avoid confusion.

As an AccidentalPlacement, it won't work very well with chords that have
accidentals far enough away from the head the glissando ends on, or
chord glissandos where some heads don't have accidentals:

\relative c, {
  \clef bass
  \override Glissando #'minimum-length = #6
  \override Glissando #'springs-and-rods = #ly:spanner::set-spacing-rods
  <cis gis' dis'>8[\glissando <d! a' e'>]
}

lily/line-spanner.cc:380: "minimum-distance "
The docstring for this will need changing.
