I issued a bugreport a long time ago about no line number given for no
pigment warnings in v3.1g. I presume this is the fix that Ron had
promised. He mentioned that it was not an easy thing to do. For example
if your no pigment warning comes from deep within a deeply nested loop
isolating the exact location and giving a line warning is extrememly
difficult to isolate. It may create more overhead than is acceptable
to get this level of error checking.
