Agreed, that’s a nice addition.

OK.

Nitpick: “modified in transit” refers to integrity, not authenticity;
perhaps write “you don’t know that the data you receive is really coming
from the specified host”?

Also maybe “lacks authentication and confidentiality”.

Perhaps “git-http-configuration->nginx-location”?

OK with changes along these lines!

Eventually we should consider adding tests for the Git services.
