I admire your ingenuity with this solution, but there's a much simpler
way of achieving this without having to use a shortcut every time
there's a problem glissando:

\version "2.11.42"
\paper { ragged-right = ##t }
{
  % default, glissando is invisible
  a8\glissando b a b
  % set spacing rods so we can override the minimum length
  \override Glissando #'springs-and-rods = #ly:spanner::set-spacing-rods
  \override Glissando #'minimum-length = #5
  a\glissando b
  \override Glissando #'minimum-length = #8
  a\glissando b
}
