Produce a useful error if /ssh_info was HTML and not plain text

If /ssh_info is protected by an HTML based login page, we may get
back a "200 OK" response from the server with some HTML document
asking us to authenticate.  This can't be parsed into a host name
and port number, so we shouldn't even try.

Valid host names and decimal port numbers cannot contain '<', but
an unexpected HTML login page would.  So we test for '<' to give
us a fair indicator that the content isn't what we think it is,
and bail out.
