Not to nitpick, but this is faster:
nc_q_param="-q"
nc_output=`LANG=C nc -q 2>&1`
case "$nc_output" in
*"option requires an argument"*) nc_q_param="-q -1" ;;
*"invalid option -- q "*) unset nc_q_param ;;
*"invalid option -- 'q' "*) unset nc_q_param ;;
esac
unset nc_output

I'd use something like this instead, in some initialization code like
e.
Various scripts rely on nc -q which is an invalid parameter on Fedora
and RHEL. Apparently Fedora defaults to the -q behavior. As a result
whenever -q is used an ugly error message is printed and nc fails.

This is a very similar issue
