I see a 4x speedup on a large Git-enabled home directory, as follows:

    $ time (git status --porcelain | wc -l)
    212
    0.01s user 0.02s system 0% cpu 9.021 total

    $ time (git status --porcelain | grep '??' &>/dev/null)
    0.01s user 0.02s system 0% cpu 12.294 total

    $ time (git status --porcelain | grep -q '^?? ' 2>/dev/null)
    0.01s user 0.01s system 0% cpu 3.097 total
