Expand description

The `ambiguous_glob_imports` lint detects glob imports that should report ambiguity errors, but previously didn’t do that due to rustc bugs.

#### §Example

ⓘ

    #![deny(ambiguous_glob_imports)]
    pub fn foo() -> u32 {
        use sub::*;
        C
    }

    mod sub {
        mod mod1 { pub const C: u32 = 1; }
        mod mod2 { pub const C: u32 = 2; }

        pub use mod1::*;
        pub use mod2::*;
    }

{{produces}}

#### §Explanation

Previous versions of Rust compile it successfully because it had lost the ambiguity error when resolve `use sub::mod2::*`.

This is a future-incompatible lint to transition this to a hard error in the future.
