bug#63861: [PATCH] pp.el: New "pretty printing" code

[Stefan Monnier]

Tags: patch

I've often been annoyed by the way `ielm` "pretty prints" data,
so I wrote my own pretty printer, which has evolved over the years.
I believe it has finally reached a state which may be acceptable
to more than just myself.

The new code is in a new function `pp-region`.
The old code redirects to the new code if `pp-buffer-use-pp-region` is
non-nil, tho I'm not sure we want to bother users with such
a config var.  Hopefully, the new code should be good enough that users
don't need to choose.  Maybe I should make it a `defvar` and have it
default to t, so new users will complain if it's not good enough?
