It doesn't suggest anything of the sort.  The two cases are not mutually 
incompatible; both are confusing and in my mind call for exercising reviewer 
discretion over the style guide.

No, *it is* an argument for reviewer discretion.  And I *do not* think the 
style guide is wrong for the *guide* to prefer "!foo" over "foo == 0"!

I just think there are exceptions.   And that in the end we have to trust in 
the compiler and the reviewer's judgement.
