E0364: Bad output for macros/no explanation of #[macro_export]

[halvko]

Given the following code: playground

macro_rules! foo {
    () => {};
}
pub use foo;

The current output is:

error[[E0364]](https://doc.rust-lang.org/stable/error-index.html#E0364): `foo` is only public within the crate, and cannot be re-exported outside
 --> src/lib.rs:4:9
  |
4 | pub use foo;
  |         ^^^
  |
note: consider marking `foo` as `pub` in the imported module
 --> src/lib.rs:4:9
  |
4 | pub use foo;
  |         ^^^

Ideally the output should probably look like:

error[[E0364]](https://doc.rust-lang.org/stable/error-index.html#E0364): `foo` is only public within the crate, and cannot be re-exported outside
 --> src/lib.rs:4:9
  |
4 | pub use foo;
  |         ^^^
  |
note: consider marking `foo` as `#[macro_export]`
 --> src/lib.rs:4:9
  | 
  | #[macro_export]
1 | macro_rules! foo {
  | 

This error does not help explain how to fix it. In addition to explaining #[macro_export], pub(crate) use foo; could also be shown, so the user can decide what they wanted to do.
