@epriestley, this linter rule would be much easier if we change the way ternary expressions are parsed (specifically, if we add n_OPERATOR nodes for ? and :)... I'm not sure if this is desirable though.

The parser change elsewhere seems correct/desirable to me.

Maybe included nested ternary operators in the test case, too, since this will also not get that quite right (the operators will be selected by both the parent and child and we'll raise extra warnings, I think)?

(We should fix this, of course, but presumably that's straightforward with the operator fix.)
