Do something sensible with rustdoc/demo.rs

[catamorphism]

FIXME says "It would be nice if we could run some automated tests on this file". Now that include_str exists, that's possible.

@catamorphism is your thinking here that we would automatically include the contents of demo.rs into another file that applies some functions from librustdoc to the included text, just to ensure that nothing hangs/segfaults? Or was there some strategy for checking that the documentation output conforms to some expected value?

(I'm in part trying to understand why include_str was the missing piece of the puzzle ... the kinds of tests I was imagining seem like they would work with files just as well as with included-strings.

(I know you didn't write the original comment, so if you don't have an idea of what the intention was, feel free to say so. :)

@pnkfelix Hmm, I no longer remember what I was talking about :-) Your reasoning seems sound to me.
