Specifically, the non-proprietary services libravatar (now default)
and unicornify have been added. The behaviour is customised via the
new variable `gravatar-service'.

Thanks.  I will let the Gnus folks to review this, but I have one nit:

> +  :version "27.1"

This should say "28.1", as the emacs-27 branch doesn't accept new
features.

Also, we need a NEWS entry describing the new option(s), and possibly
also a corresponding change for the Gnus manual.

If you make this an alist then your cond below becomes just
'alist-get', and you have the URLS in just one place.

This is changing the default from gravatar->libravatar, won't that
break stuff?

git format-patch HEAD~ + attaching the result will work as
well, assuming your MUA doesnʼt mangle patches :-)

If the avatars are still resolved, then I think thereʼs no issue with
changing the default (especially considering it wasnʼt configurable
before). Thanks for clarifying.

In that case I'm attaching the patch to this mail, I hope Gnus handels
it corretly.

This is missing a ChangeLog style comment. There are various ways to
produce that, the easiest is probably:

C-x v d ; vc-dir
m ; mark the files you want to commit
v ; vc-next-action, which will put you in a commit message buffer
C-c C-w ; this will look through the diffs of the files youʼre
        ; commiting and pre-populate the commit message with
        ; file/function/variable names. You then fill in the details
        ; of what you changed.

Of course, a preamble like you had explaining the 'why' of the change
is also good.

See "** Commit messages" in CONTRIBUTE for a more detailed description
of the desired format for commit messages.

We normally call these 'user options', and donʼt use back-quotes in
NEWS, and try to have the first line be a complete sentence, so:

** Gravatar

===
*** New user-option 'gravatar-service' for host to query for gravatars.
Defaults to Libravatar, with Unicornify and Gravatar as options.

Thanks for your patch.

I have been trying what you mention and what the "Commit message"
section describes, but I just cannot execute C-c C-w, nor
can I find it anywhere. What command is it supposed to call? We are
talking about the "*vc-log*" buffer, aren't we?

I'll just use your log message, it sound a lot better.

Assuming you are running Emacs 27, then yes, it should work in the
*vc-log* buffer.

    C-c C-w runs the command log-edit-generate-changelog-from-diff (found
    in vc-git-log-edit-mode-map), which is an interactive compiled Lisp
    function in ‘log-edit.el’.

Thanks, much better. Eli, is this a small enough change to commit as
'Copyright-paperwork-exempt'?

I actually signed the copyright assignment last year, for contributing
to an ELPA package. I thought that applied to the Emacs core too?

There's no need, since Philip has an assignment on file.

But I didn't understand how was the issue of preferring Libravatar
resolved?  Didn't someone say it wasn't a free service?

The assignment is for Emacs, and it applies to ELPA as well.

No, I might have said that Gravatar is non-free, and as such shouldn't
be the default.

Right, and the default will become Libravatar, which is a free
service.

Here you do the SRV lookup for the TCP service, but I believe thereʼs
an HTTPS service type available as well. Could you look that up first,
then the TCP one, then fall back to the default libravatar URL?

You're right, I missed that. This patch checks the avatar-sec and avatar
record. I rewrote it a bit, to avoid duplication, so I hope the style is
ok.

Thanks. Pushed to master as 421eeff243 (with my typo in NEWS fixed).
