The current algorithm for nested pairs (those where the open and close are different, like parens and braces) simply counts open and cloes as it finds them. But it could be smarter by paying attention to the syntax of each character (ppss).

For example:

(message "finding (, huh?")
                  ---------

If the cursor is anywhere past the paren inside the string, it will incorrectly identify the underlined portion as the pair instead of matching with the first paren before "message".

For this particular case, it would work if we use syntax-ppss and note that we started outside of a string, so we should ignore the paren inside the string. Would work for skipping over comments too.

On a similar note, we could figure out which direction to search for quotes. If we are on a closing quote in a comment and the next quote is not in a comment, we should try the other direction.

To reproduce: M-' i [

[blah]
   ^

For example given the text (foo). When the point is at the opening brace and I call surround-delete or surround-change, I only get a message: surround--find-char-nestable: Did not find (

This is true for (, [ and {, but it does work for " and '.
