This is correct.

Strange. The function font::load_desc (in font.cpp) calls
font::open_file (in fontfile.cpp) which in turn calls
font_path.open_file, where font_path is a search_path which explicitly
uses $GROFF_FONT_PATH. Looking into searchpatch.cpp you can see that
search_path::search_path loads the contents of GROFF_FONT_PATH with
getenv. Please insert some code there to print the value of
GROFF_FONT_PATH to stderr.
All mentioned files are in src/libs/libgroff.
