23.0.60; Displaying PPM

[Markus Triska]

When I open the file http://www.logic.at/prolog/problem.ppm with

   $ emacs -Q problem.ppm

it is not displayed correctly. Showing it with

   $ display problem.ppm

works.

When I open it with GIMP, it tells me "PNM: Invalid maximum value".

The PPM file was created with "convert" from this PostScript file:

   http://www.logic.at/prolog/demo.ps

and it seems to satisfy the constraints from:

   http://netpbm.sourceforge.net/doc/ppm.html

I've fixed this problem in the EMACS_22_BASE branch so it will be in the 
next version (whether that is 22.3 or 23.1 is undecided). I also passed 
the bug report on to the GIMP team, where they have changed the wording 
of their error message from "Invalid" to "Unsupported" pending a proper fix.
