Maybe you can write something up on the wiki about what methods you used to
check and how people can do that again.

We don't have a clear rule about (! foo) vs (!foo) and I don't find either
one particularly bothersome.  So I'm inclined to avoid the churn of changes
just for that.  That looks like be a lot of the lines touched here.

All these sorts of ones can go under the "obvious enough" rule any time.
I'd say the same for leading spaces->tabs.

Here you should just drop the superfluous braces too.


Thanks,
