Lint to avoid putting newlines in links or variables

[tabatkins]

Request from a fellow Chromie: a lint that warns if you have broken a link or variable across lines, as that makes it harder to search for terms in the source later.

I should be able to do this now, by walking the document. I can possibly do it better with the parser rewrite, but I don't think I need to wait for that; it'll just give me better line numbers in the error.

I think I disagree with this change. The specs I work on generally follow the HTML Standard style guide, which allows for line breaks in between words in a dfn or link, or even within tags associated wtih those dfns or links. All of those specs will I guess just be broken now if they treat warnings as fatal? That seems bad and backwards incompatible.

Lints are always optional, and this would be default-off, like most of the lints are.

I'd be interested in this but it would be a prerequisite to be able to toggle on or off specific lints, since we'd want this one off but other lints on for some specs. (And both this and other lints on for other specs.)

[tabatkins]

You can already do that by specifying the Complain About metadata. Or were you talking about something else?

I guess it might be a documentation problem, but I didn't realize "lints" were the same as "Complain About".
