Dealing with that is definitely the least pleasant part of trying to
maintain docs...

I'm not convinced that "Ex." is a clearer or more readable syntax, and
I'd prefer to avoid adding to the regex hell that kernel-doc already is
or adding more special syntax of our own.  How about, as Lukas
suggested, just using the "::" notation?  You get a nice literal block,
albeit without the syntax highlighting -- a worthwhile tradeoff, IMO.
