Oh, there's been a TON of work on this.
(1) back in the day, it was an enormous area of work: not so much "error-recovery" but "error-detection with most-perspicuous-possible error-messages, including if possible examples"
(2) I know that Menhir (the Ocaml parser-generator) has some support for this.
(3) I know that in fact, this is a good reason to WANT to use a parser-generator -- b/c the GRAMMAR will allow you to detect many cases of syntactic errors automatically.
