Looking for a way in #emacs to have quoted text in emails collapsed in message-mode.

I envision something like have it all collapsed and replaced by something like '[...]' which could then be used as a toggle.

Anyone have any pointers before I dive into regex hell to write my own.

The best I could find is https://www.emacswiki.org/emacs/HideShow which seem to provide a generic solution which could be adapted.
