I think you're right. But if there is unbalance and one of the following
is true:
* the first non-string position searching backwards from (window-end)
downto (point) is sucessfully asserted to be outside a string, or
* there are no strings at all between (point) and window end (basically
implies the previous point).
then I think it is doable, i.e. there is a case for autopairing despite
the unbalance. Not sure how useful, though. Needs prototyping, and I'm
not super-motivated to do it right now.
