Doc comments on links

[kw217]

The current error_chain! macro permits doc comments on errors, but not on links:

    error_chain!{
        links {
            /// Doc comment for links
            LinkedError(super::databases::Error, super::databases::ErrorKind);
        }
    }

yields

error: expected ident, found #
  --> src/lib.rs:11:13
   |
11 |             /// Doc comment for links
   |             ^^^^^^^^^^^^^^^^^^^^^^^^^

whereas doing similarly for an error in errors works just fine.

See a full failing example here - if line 11 is a normal comment, the compiler emits a warning; if it's a doc comment, it fails.

Yeah I know, see #63 (the comments are converted to the #[doc = ...] form. If you find a working solution, I take it!

Thanks, sorry for duplicating!
