Address code-review comments

- some wording changes in included documentation
- find supports multiple starting paths, we don't need to launch it 3 times
- Change the regex that trims the file extension to only trim the last extension

Some additional things I noticed:

- find should use -L to see through symlinks like the autoload processing does.
- find should check the user's autoload directory first, so users can override
  Kakoune's built-in documentation.
