I don't believe there is such a thing as `this' quoting, only 'this' and
"that" (string quotation) and `the other` (symbol quotation).

On the other hand, there is definitely a bug with ESS's string highlighting:

Though " ' " correctly recognizes that the ending quote-mark ends the
string, ' " ' does not.  This is inconsistent with R's parser and also
inconsistent with ESS itself, which correctly implements forward-sexp etc.
over these expressions.
