Autotest: simplify logic to compute test group result.

[Ralf Wildenhues]

This small cleanup goes on top of the color test, but only because same
text area is edited; reversing that order is trivial of course.

The patch is easiest to verify if you take the old file, move down the
first case as far as possible, and the last one up as far as possible.
They meet in the middle.  :-)

OK?

Thanks,
Ralf
