Clean up instances of if (cond && !func())

[cadmic]

for instances of

if (cond && !func(...)) {
    return false;
}

where cond is a "check something" thing and func is a "do something" thing, rewrite this as

if (cond) {
    if (!func(...)) {
        return false;
    }
}

I find this easier to read since the if (!func(...)) return false; is standard boilerplate and isn't really part of the condition.
