Oh. In that case, why do we even check for its stdout?
(from rev-lists man page)
--quiet
Don’t print anything to standard output. This form is primarily
meant to allow the caller to test the exit status to see if a range
of objects is fully connected (or not). It is faster than
redirecting stdout to /dev/null as the output does not have to be
formatted.
