If you send something like "PUT / HTTP/1.0" to something derived from
BaseHTTPServer that doesn't define do_PUT, you will get a response
that begins like this:

	HTTP/1.0 501 Unsupported method ('do_PUT')
	Server: SimpleHTTP/0.3 Python/1.5
	Date: Tue, 30 Mar 1999 18:53:53 GMT

The server should complain about 'PUT' instead of 'do_PUT'.  This
patch should fix the problem.
