Change in v3 since v2:

When I read the previous version of this series, I found that many of
the instances where test_line_count_cmd() were used became quite
noisy, to the point that it was difficult to see at-a-glance the
command being tested. As an experiment, on top of your patch 1, I
crafted a patch which made `--out` and `--err` optional (defaulting to
`--out`). That helped reduce the noise level a good deal, however, I
still found it too noisy. Consequently, I crafted a second patch which
renamed the function to test_output_count(), and only then did the
noise level drop sufficiently that the command being tested didn't
entirely disappear into the background.

Since you've dropped the `--out` and `--err` options entirely, I
wonder if now would be a good time to shorten the function name, as
well, in order to further reduce the noise level. Since it now only
tests stdout (and doesn't deal with stderr), a name even shorter than
what I tried for the last version might be even better. So, for
instance, the name test_out_count() might not be too bad:

    test_out_count = 0 git ls-files -o &&
