Cut off glisando at barline without change of direction?

[Peter Terpstra]

Dear people,
I would like to cut off the glissando at the barline.
When the Glissando.to-barline override is used the glissando's are
concentrated at the barline, i don't want them to change direction like
that.
Is there a way to prevent this or is the another a way to cut off the
glissando without changing direction?

Thank you so much in advance!

Peter

Example:
\score {
  \relative c'' {
   \time 1/4
   \override Glissando.to-barline = ##t
   <a e' fis>-\tweak measure-length #2 \glissando | <g b d>
  }
}
