This is nearly there, thanks!

I think we need a better name than "TEST_WRITE_OUTPUT". That variable
could be about enabling some tests of writing output or several other
things. How about TESTREPORT_FULLLOGS?

The variable name needs to be mentioned in the commit message and we
should cc: Scott so we can add to the manual.

Cheers,
