Use ws-butler when enabled and available.

When having auto-save on and you edit text the cleaning up of
white-space is a bit intrusive and removes the space at the end of the
line where you are writing. ws-butler-mode is an alternative that does
take this into account.

I understand if this might be unwanted, but I am opening this in hope that it would help someone else and to open a discussion. Perhaps as an alternative to implement the unobtrusive change in editorconfig-emacs itself.

Thanks for your proposal! 👍
I agree it needs some more consideration, I'll try it later!

I pushed a new commit to add a new variable editorconfig-trim-whitespaces-mode instead.
With this now you can use ws-butler by adding following:

(setq editorconfig-trim-whitespaces-mode
      'ws-butler-mode)

I haven't check if this code acrually works yet, I'll do shortly!

I've checked it works!

Nice solution, this should cover all use cases when it comes to whitespace trim configuration. Thanks, this has been a longtime itch of mine.
