The pgmcolor program for artificially coloring gray scale images was
posted to alt.sources on Nov 19. I received a patch from Brian
Reynolds fixing two bugs that somehow didn't show up on my system:
missing types for argc and argv in main() and a missing memory
allocation via pgm_allocrow() in doAbsolute().

So now the original should be called version 1.0 and the new program
is 1.1. I'm sorry about the format of the patch: it's a context diff,
not a "new style context diff". Anyone know where to get the new diff
program?
