minor fixes

Some minor fixes.

These should probably go into one of the regular clean-up commits.

Description of your pull request and other information

This fixes some extra whitespace in messages (probably introduced by stripping "`").

It also fixes use of IENAME, as inherited from youtube-dl. It was already wrong there, see the partial fix ytdl-org/youtube-dl@fc86d4e.

Note: flake8 yt_dlp/utils/_utils.py does not fail due to my changes.

The spaces are intentional, they are suppose to be the signifying code or links. Please revert

Okay, reverted. (With a commit, since we're not supposed to force-push, right?)
