This is for proposal: rust-lang/libs-team#250
The original check-in (#114136) contained both methods retain and retain_mut, which does not conform to rust-lang/libs-team#250 (comment).
I updated the retain documentation to specify &mut e, removed the retain method and renamed retain_mut to retain to conform to the request.
The pull request doesn't really contain much that is new, just removes the unwanted method to meet the requirements.
I've run the tests "library/alloc" on the code and no issues.
Hopefully I'm not stepping on the original author's toes. I just ran across a need for the method and wondered why it was unstable.
