I omitted the -q in my patch because according to the GNU grep manual:
Portability note: unlike GNU grep, traditional grep did not conform
to POSIX.2, because traditional grep lacked a -q option and its -s
option behaved like GNU grep's -q option. Shell scripts intended to
be portable to traditional grep should avoid both -q and -s and
should redirect output to /dev/null instead.
However, since we can be assured that this code will only be executing
on HP-UX (and if HP-UX's native grep supports -q), I think it can go
back in.
