parallel testing when STDOUT is not a terminal

[David Golden]

I've discovered that having HARNESS_OPTIONS=j9 is not a nice thing to
set as a default.  Test output for CPAN::Reporter winds up really
screwed up, as shown below.  Is there a non-ornamented way of running
tests in parallel?  I.e. running them in parallel and getting just
summary output rather than watching the little bars grow across the
screen?  Or perhaps this is something like colors where it needs to
happen automatically if STDOUT is not a terminal.

Regards,
David

[Note -- in vim, I saw carriage returns at the start of every "=" line.]
