```
warning: unresolved link to `m`

= note: `#[warn(broken_intra_doc_links)]` on by default
= note: no item named `m` is in scope
= help: to escape `[` and `]` characters, add '\' before them like `\[` or `\]`
```
After:
```
warning: unresolved link to `m`
--> m.rs:1:6

1 | /// [value@m]
| ^^^^^^^ help: to link to the macro, use its disambiguator: `m!`

= note: `#[warn(broken_intra_doc_links)]` on by default
= note: this link resolves to the macro `m`, which is not in the value namespace
