"Flat is better than nested."
Move the long-winded, multiply-nested -R support out of runtest() and into some module-level helper functions. This makes runtest() and the -R code easier to follow. That in turn allowed seeing some opportunities for code simplification, and made it obvious that reglog.txt never got closed.
