Yes, and earlier this week I found a bug in version.c just by trying to
increase code coverage with test cases. :-)

The kind of blind application of methodology I had in mind was more
along the lines of "OK so I'm required to write unittests for
everything, so let's just pad the tests with inane stuff like 1+1==2, or
testing that the function's return value equals itself, 'cos it's Friday
afternoon and I wanna go home".
