Description
I have a very simple example where using wrap_comments lead to the doc line being wrapped even if it is exactly 80 characters.
/**
* A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A
*/
fn main() {}
I played around with comment_width and it wrapped this line even with comment_width = 83 but stopped wrapping with 84 so somehow the wrapping is off by 4 here.
Also interesting if I do the same with 100 characters and comment_width = 100 it also wraps and if I increase the comment_width it still wraps always, regardless how high I set comment_width.

Research direction
Start by reproducing the supplied Rust snippet with wrap_comments and several comment_width values, including the 80-, 83-, 84-, and 100-character cases. Trace the comment-wrapping entry point and add a regression test covering the boundary and persistent-wrapping behavior. Done means comment lines wrap at the configured width without the reported four-character offset.
