Feature request: trim at line change

[fleutot]

I highlight trailing whitespace in bright red.

Steps:

• add a new line to source code, so that the new line is automatically indented (e.g. after a curly in a C-like language),
• navigate away from the line, C-n.

Result:

• the indentation whitespace on the newly created line is highlighted, until I save the file.

Solution:

• do the trimming at leaving the line, or give an option to do so.

This is what keeps me using ws-trim instead of ws-butler. Would you consider implementing something like this?

Just out of curiosity, what is it about ws-trim that makes you want to stop using it?

@phil-s The fact that it's not in melpa. I started a new init.el from scratch when I moved to emacs 28, and I couldn't find that functionality anywhere. Until I realized I had ws-trim.el manually downloaded.
