Patches that only change coding style pollute the change history. I agree with you - the problem is that style issues should not have existed. But when they do it becomes a problem to remove them and a problem to keep them - for instance us who try to be compliant by having style helpers in our editor, we end up having to manually revert old style mistakes back in to avoid making unrelated whitespace changes or similar. I think what we get with this patch set is that there's a way to rein in the issues and to enable some regression testing without enforcing a lot of work or annoying history issues *right away*. That way this problem can be tackled when appropriate for the subsystem in question, and the reason for holding back on some changes can be documented in the local runchecks.cfg file, focusing willing helping hands on the issues considered most important for that subsystem.
