To complicate things slightly, I have a patch languishing in my
"get back to at some point" pile for enhancing the use of prefix
arguments when filling text:

https://lists.gnu.org/r/emacs-devel/2016-11/msg00300.html

Reviewing that thread, employing C-u C-u arose:
https://lists.gnu.org/r/emacs-devel/2016-11/msg00313.html

My suggestion there for C-u C-u was:

I think we could blend the 'nosqueeze' option into all this, but if
the new changes could happen in a way which wouldn't create any serious
conflicts for the other changes I'm still hoping to get made, that
would be grand.

Or if someone is motivated, please feel free to run with what I'd
already done.  I may have some more-recent local WIP on my other
machine; I'll have a look for that later.
