Issue Description:

I just read up on "Swift String Extended Delimiters" - I want to use #" and "# to enclose a String constant.

What I need is a single quote, so thought I'd use #"""# - but Xcode complains and says its an unterminated string.

The specification as written should allow my example above (IMHO).

This is an unfortunate oversight in the parser. Your interpretation is correct, and thankfully we can fix this without worrying about a source break because of the hard error.
