If a script is run with --o, G_parser() will set GRASS_OVERWRITE=1,
which has the same effect as passing --o to every module which is run
from the script.

Similarly, passing --q or --v will set GRASS_VERBOSE to 0 or 3
respectively, which has the same effect as passing --q or --v to every
module which is run from the script.

Rather than checking whether --o, --q or --v were used, you should be
checking $GRASS_OVERWRITE and/or $GRASS_VERBOSE instead. If those
variables are set, the script should behave the same way regardless of
whether they were set by --o, --q or --v being passed to the script or
set by other means.
