Hi Deri, I agree that altering the default to obtain the old `faulty' behaviour is a good idea.

These two are the same as far as implementation goes?

Is this one needed? It's an extra thing to implement, document, and test, and environment variables are, by design, fairly polluting. Is pdfpic groff-specific? A quick look suggests groff's environment variables begin `GROFF_', and that helps when the environment is examined and one wonders what cares about the ton of stuff in it these days. -- Cheers, Ralph. https://plus.google.com/+RalphCorderoy
