If you use test-groff, would you find the script more useful, less useful, or unchanged in its usefulness if it were to honor your current environment's settings of GROFF_BIN_PATH, GROFF_FONT_PATH, and GROFF_TMAC_PATH? (Its current behavior is to ignore any values in these environment variables, in contrast to an installed groff, where these environment variables affect various search paths.)
This question came up in http://savannah.gnu.org/bugs/?57630, but few users of this script are likely aware of this bug report, so I'm soliciting input from a wider audience.
