That's a fair point.

If your argument was "this is dead code, and should be removed to help
future maintenance", I'd have no problem with that. My point was
simply that I think that adjusting the code to make the coverage stats
hit 100% feels like going at things the wrong way round.
Is it really that difficult to simply tell coverage to ignore them? I
thought someone had already pointed to a coveragerc file that let you
