Hmm, so this change will permit long lines anywhere that there is a word beginning with ../. I'm not sure if this is what we want. Maybe it is, or maybe it's too accepting.

On the other hand, if we only keep the second change, below, then the [deref-coercions]: link in the relevant PR would put us into the EXP_URL state, and there we can accept ../, where the context is a bit less ambiguous.

I could go either way, just saying that maybe we don't want this line.

There is currently one line in the codebase which would be affected:

$ git grep -E '\s?//(/|!)?\s\.\./'
src/libstd/net/tcp.rs:    /// ../../std/net/trait.ToSocketAddrs.html#tymethod.to_socket_addrs

It is part of a Markdown link.

I'm in favour of removing (though I think it's just the first word on a line, rather than any).
