Don't trim trailing whitespace from doc comments

Don't trim trailing whitespace from doc comments as multiple trailing spaces indicates a hard line break in Markdown.

I'd have liked to add a unit test for `docs_from_attrs`, but couldn't find a reasonable way to get an `&Attrs` object for use in the test.

Fixes #15877.
