[cfe-dev] parentheses flag warning

[David Blaikie via cfe-dev]

GCC doesn't seem to warn on this either. On the basis of the original
warning I could see how this case could merit similar handling - but I
doubt we'd want to add that handling to the existing flag at this point
(due to the number of people over the decades that have used the warning
for the behavior it currently provides, not expecting the new/additional
behavior for the ternary operator or other bool-testing assignment
situations (eg: "void f(bool); f(x = 5);")
