One is using git:, the other one https:. I don't know if they support
other protocols. One of them is on github (https), the other one is the
emacs repo (git://git.savannah.gnu.org/emacs.git).

I don't have ssh access to any of the remote hosts. Both repos, I can
only clone/fetch/merge from.

But I don't want to fetch? If I can fetch only the data (a minimal
amount of data) I need to figure out if the remote is more recent,
that's ok, though.
