[RFH] Issues and Contributions to friendly third-party projects

[Junio C Hamano <gitster@pobox.com>]

After seeing a issue report on git-scm.com (and remembering number
of issues reported on friendly third-party projects on this list
and getting redirected to elsewhere), it may probably make sense to
document who they are, what they do, and how to contact them, in the
same document that drove these contributors to this list in the
first place.

I am still not sure which of our document is the best place to do
so, but no matter where it eventually goes, it would be better to
first agree on 

 - if doing so is a good idea to begin with (such a list in a
   document will incur maintenance cost)

 - who to include on such a list (the list will become useless if it
   includes everything on earth that claims to be related to Git;
   where do we draw the line?)

 - how the list will be maintained (are we responsible to ping them?
   will they update us to keep their entry from going stale?)

As a discussion starter, here is what I added to the source to "A
note from the maintainer" message I send out every once in a while
(https://lore.kernel.org/git/xmqqr05a5wjv.fsf@gitster.g/ is the last
one I sent out).

Comments?  Corrections?  Opinions?

Thanks.
