I don't know if static checkers care about whitespace and indentation in C;
it might be a very obvious thing to do for Python programmers, but maybe not
for C static checker developers :)

And probably with good reason, since whitespace isn't a consideration except
for nicely readable code, which many people (not talking about CPython here)
apparently don't care about, you'd have tons of spurious checker messages.

In many cases (especially error handling ones like "goto fail"), I expect the
checker to flag the error anyway, but for semantic reasons, not because of
whitespace.
