Details:
The test-groff script simulates an installation by defining its own
GROFF_BIN_PATH, GROFF_FONT_PATH, and GROFF_TMAC_PATH values pointing to the
build directory.
Unfortunately, instead of appending to any existing values of these variables,
it overwrites them, so the user's environment is ignored.
For this script to more closely emulate running an installed groff, it should
prepend any existing values to the ones it defines. This would make it treat
these variables the way a groff installation would, searching the user's
environment (if any) first, then the "system" one.
For example:
if [ "$GROFF_FONT_PATH" ]
then
GROFF_FONT_PATH="$GROFF_FONT_PATH$SEP"
fi
GROFF_FONT_PATH=$GROFF_FONT_PATH\
[... rest of script's normal definition for this variable ...]
