Significantly improved accuracy of in-line delimiter matching

Browse Source 
Previously the following would've caused everything after the `/` to be
italicised (until it found a second `/`).

    foo/bar

The same happened with all of the other in-line delimiters.  This was
clearly not good enough.

The new in-line delimiter matching is now much closer to Emacs' than
before while maintaining Unicode support (as well as Vim can offer).
