Comment # 8 on bug 859554 from Wolfgang Bauer

I suppose this can be closed meanwhile.

13.1 is no longer supported since a long time (I think even Evergreen support
has ceased completely since a while), and this bug was/is fixed in later
versions (13.2 and Leap 42.x come with ghostscript 9.15).

Btw, I did look at backporting the patch to 13.1 over 3 years ago, but gave up
trying to rebasing it because of the massive changes (also in the file
structure).
