Michael wanted a general approach to requiring specific GNU ELPA package
versions; he suggested an implementation which I adapted and pushed to
master.  You can try it by alternating between revisions
a1c767fe56acfed6627682fadc337203f3b8678c and
4edcba28826869b07f622fd83f6aab96fd8e4d19 of web-server.el and confirming
that for the former commit the tests are skipped and for the latter,
they're run.

I also tested how url-retrieve-synchronously behaves with NTLM
authentication when the authinfo password is wrong.  It doesn't
infinite-loop -- it tries once with the authinfo credentials and if they
fail, it prompts the user for a username and password.  Therefore, the
patch that caused the regression isn't needed for NTLM and the
workaround patch I pushed is fine as-is.

I'm marking this bug done.

Thanks,
Thomas
