Details:

"demo hold 6" quite reliably causes problems when printing to EPS format (see
bug #55529)


for ii=1:100
  ii
  demo hold 6;
  ## axis auto
  print toto.eps -depsc ## -loose
  close all
endfor


This leads to either a crash of Octave, a hang with Ghostscript consuming 100%
CPU or a simple error due to Ghostscript returning a bad status.

This example doesn't crash, hang or error out if I use "axis auto" prior to
printing, so that bug #48689 doesn't come into play. Though, the output figure
has a wrong bounding box. See attached "bad_bbox.eps".

This example works perfectly well when using the "-loose" print option (which
used to be the default in 4.4). So it looks like epstool has problems cropping
some of our gl2ps generated EPS files.
