~ and + combinators don't work

Line 190 in 93a1273

if (!matchRight(node)) return false;

The calls to matchLeft() and matchRight() are incorrect; they need to pass the parent and index down. As in, matchLeft(node, parent, i) and matchRight(node, parent, i). Otherwise, when using multiple combinators, the parent is never passed down, and will always be undefined, so lines 195 and 202 will always trigger, and return false.

Ah good catch, thank you for raising that! If you're up for a PR that would be very helpful, otherwise it might take me a bit to dive back into cleaning up the issues here.
