We made this change because users complained about unhelpful error
messages when they tried to connect to a server that did not even
implement HTTP/DAV. The error message was "Malformed XML in response"
which wasn't exactly helpful for diagnosing the problem.

I admit I didn't have GitHub in mind when I added this check. ...

I keep wondering why the GitHub staff didn't contact us when they
implemented their SVN-like server. This might all have been avoided if
they had. We already spent time trying to work around GitHub's faulty
implementation (q.v. r1707164), but there's a limit to how much we can
or should do. The protocols in question are quite well documented after
all, both in RFCs and in our own notes.
