doc_overindented_list_items is too aggressive for argument lists

[asomers]

The new doc_overindented_list_items lint makes sense in many cases. But I think it's too aggressive when it comes to argument lists. These are usually formatted in two columns, and the lint triggers if the text in the right column contains multiple lines. A real-world example from Mockall is:

    /// # Arguments
    ///
    /// * `modname`:    Name of the parent struct's private module
    /// * `self_args`:  If supplied, these are the
    ///                 AngleBracketedGenericArguments of the self type of the
    ///                 trait impl.  e.g. The `T` in `impl Foo for Bar<T>`.

Another example that I found online is rust-lang/rust#57525 .

Should this lint be toned down, or is there a better way to format argument lists? In the Mockall example, the documentation is for internal use only; it isn't even generated on docs.rs. So I don't want to sacrifice readability of the source just to improve the non-existent HTML.
