I like the rationale behind this, but fwiw. I already had a patch that
was ejected for this:

    http://article.gmane.org/gmane.comp.version-control.git/146566

Quoth Junio:

    "Besides, "make -j15 test" from the toplevel already runs the
    tests in parallel.  I don't see much point in this change."

But I'd like to have it so that I could `make && make test_harness`
and get readable test output.

But we should probably be using t/harness to run them, not
prove(1). Then we would make the test_harness target respect the
HARNESS_OPTIONS variable, which I e.g. have set to HARNESS_OPTIONS=j9
on my system.
