I have a similar problem. Steps to reproduce:

1. cargo new --lib example
2. cd example
3. cargo add iota-types
4. cargo +nightly doc

rustc +nightly --version -v

cargo add iota-types

Same issue also reproduces when iota-types is documented directly, not as a dependency.

[petrochenkov]

The link in iota-types looks like this

    /// Creates a new [ GovernorAddressUnlockCondition`].

, not the single backtick and also whitespace.

Looks like a mismatch in preprocessing the stuff inside [...] between rustc and rustdoc.
