One problem is that the content body sent along with the error is not
necessarily appropriate for showing to the user (e.g., if it is HTML, it
is probably not a good idea to show it on the terminal). So I think we
would want to only show it when the server has indicated via the
content-type that the message is meant to be shown to the user. I'm
thinking the server would generate something like:
HTTP/1.1 403 Forbidden
Content-type: application/x-git-error-message
User 'me' does not have enough permission to access the repository.
which would produce the example you showed above.
Actually, isn't the human-readable part of the server response meant
for this kind of thing? I.e.
HTTP/1.1 403 User 'me' not allowed to accept the repository.
