FWIW in other cases Eric & I have just been putting the source in
comments in the actual test file - makes it obvious. I probably
wouldn't think to look in other files to find the source the test case
was generated from. (though, admittedly, it is a little easier to
build the test case when the source is there, rather than having to
copy/paset it out, trim the comment characters, then compile it)
