Use `grep &>/dev/null` instead of `grep -q` when operating on piped stdin.
`grep -q` may exit as soon as it finds a match; this is a good optimization
for when the input is a file. However, if the input is the output of
another program, then that other program will receive SIGPIPE, and further
writes will fail. When this happens, it might (bsdtar does) print a
message about a "write error" to stderr. Which is going to confuse and
alarm the user.
I'll add that this is not purely hypothetical--it has happened to me while
running the test suite.
