Glissando avoid accidental bug?

[Nick Payne]

Regardless of whether I set the end-on-accidental override to true or
false, or omit it completely, the glissandi don't stop short of the
accidental.

\version "2.17.5"

\relative c'' {
  \accidentalStyle "modern"
  \override Glissando #'(bound-details right end-on-accidental) = ##t
  c1\glissando cis\glissando c
}
