That sounds like it'd help if we have any lingering cases where the
text after the PASS: etc. isn't unique, since otherwise it's probably
unpredictable which one comes first in the combined summary (as it was
when the test order was still keyed only off filename).  OTOH I suppose
we should just fix those tests so that the name is unique.

Also, now that even partial RUNTESTFLAGS-based testuite runs can be
fully parallelised (very nice, thanks), what -j1 did is probably
no longer relevant anyway.
