(w3m-w3m-get-header "http://server/")
 => "HTTP/1.0 200 Document follows

Server: NCSA/1.4.2

"
という Response を返すサーバが社内にあったのですが、

(w3m-w3m-attributes "http://server/")
 => nil

となってしまいます。

RFC 1945 によると、"HTTP/1.0 200 " 以降は任意みたいですので、
以下のようにしました。

	* w3m.el (w3m-w3m-attributes): Don't check "OK" string in Status-Line.

6.1  Status-Line

   The first line of a Full-Response message is the Status-Line,
   consisting of the protocol version followed by a numeric status code
   and its associated textual phrase, with each element separated by SP
   characters. No CR or LF is allowed except in the final CRLF sequence.

       Status-Line = HTTP-Version SP Status-Code SP Reason-Phrase CRLF

   Since a status line always begins with the protocol version and
   status code

       "HTTP/" 1*DIGIT "." 1*DIGIT SP 3DIGIT SP

   (e.g., "HTTP/1.0 200 "), the presence of that expression is
   sufficient to differentiate a Full-Response from a Simple-Response.
   Although the Simple-Response format may allow such an expression to
   occur at the beginning of an entity body, and thus cause a
   misinterpretation of the message if it was given in response to a
   Full-Request, most HTTP/0.9 servers are limited to responses of type
   "text/html" and therefore would never generate such a response.

6.1.1 Status Code and Reason Phrase

   The Status-Code element is a 3-digit integer result code of the
   attempt to understand and satisfy the request. The Reason-Phrase is
   intended to give a short textual description of the Status-Code. The
   Status-Code is intended for use by automata and the Reason-Phrase is
   intended for the human user. The client is not required to examine or
   display the Reason-Phrase.
