[NonGNU ELPA] New package: eldoc-diffstat

[Johann Klähn]

I would like to submit a new package to NonGNU ELPA: eldoc-diffstat.

  https://github.com/kljohann/eldoc-diffstat/

It provides a way to display VCS diffstat information via eldoc.  I.e.,
if point rests on a commit in a magit, vc-annotate, or log-view buffer,
the Git or Mercurial diffstat summary will be shown in the echo area.
For example (though it uses ansi-colors and fontification, so you might
prefer to look at the screenshot in the repo):

It's adapted from Tassilo Horn's 2022 blog post “Using Eldoc with Magit
(asynchronously!)”:
