pnmtoimage can't read conformant pgm/pnm files according to 
http://netpbm.sourceforge.net/doc/pgm.html specification.

Issue 294 only partially solve the issue.

before r2942,

OpenJPEG failed to read data/baseline/conformance/a6_mono_colr_0.pgm

head -2 data/baseline/conformance/a6_mono_colr_0.pgm
P5
3323 891 255

Because it was expecting
P5
3323 891
255

The issue has been corrected for this specific PNM header disposition

A conforming header could be like :
P5 3323 891 255
Or
P5 3323
891 255
Or
...

In those cases, OpenJPEG would fail to read the file.
