While working on the bug 'Changing package source URLs from git:// to
https://' [0], I noticed an issue with the sources for guile-emacs.
We currently fetch this source code over the unauthenticated GIT
protocol. It is also available over HTTPS. However, these two protocols
are returning different Git repos for some reason. For example, with the
diff shown below [1]:
------

The clone times out for me:
--8<---------------cut here---------------start------------->8---
git clone https://git.hcoop.net/git/bpt/emacs.git guile-emacs-over-https
Cloning into 'guile-emacs-over-https'...
^C
--8<---------------cut here---------------end--------------->8---
But the clone from git:// works fine.
Is the repository actually served over HTTPS?

Don’t mind me. It eventually worked. The repositories have different
histories, and the https-repo looks like it is two commits behind.
Looks like an older rebase.
I’d say we should leave it with the current git:// URL.

The thing is, since the git:// protocol is unauthenticated, we could
assume that those extra two commits are added by a MitM :/
Somebody who is interested in guile-emacs should really ask upstream
what is going on.

Since we hash the checkout's contents, an attacker would have to be very
consistently adding those two commits for both the original packager
(me) and all subsequent users... a possible attack, but I think it's not
the biggest thing to worry about.

The issue seems to have been resolved upstream, because HTTPS and git://
clones now return the same repo. I adjusted our guile-emacs package
accordingly in commit ef5fa91ccc5d6ff7a5ce21df19541b57b98db4c7
