The pnm specs say that anything starting with a "#" is to be
considered a file note (comment) until the next line. That program is
not conforming to the pnm specs.

From pbm (5):

- Characters from a "#" to the next end-of-line are
ignored (comments).

(People from the Unix arena rather have everybody follow the specs
instead of everybody creating ad-hoc workarounds for every bug that
crops up. Please complain to the Impos/2 people about this.... ;-)

(Unix people also like to make small tools that do just one thing.
How a about a de-comment tool.....)

Regards,

Roger.
