[TUHS] Proliferation of options is great simplification of pipes, really?

This proposal reminds me of Paul Glick’s lp command.  It took whatever file you gave it, and processed
it as necessary for whatever printer you chose.  It was very useful, simple AI.

Modern processors are fast enough, and groff input small enough, that the "extra" pass wouldn't be burdensome. And it would take the burden off me to remember exactly which preprocessors are essential. -- jpl
