>Summary: BaseHTTPServer; HTTP/1.1 spec not "vague"

Initial Comment:
The module docstring for BaseHTTPServer says

    The protocol is vague about whether lines are
separated by LF
    characters or by CRLF pairs -- for compatibility
with the widest
    range of clients, both should be accepted. 
Similarly, whitespace
    in the request line should be treated sensibly
(allowing multiple
    spaces between components and allowing trailing
whitespace).

HTTP/1.1 is not vague.  It says in section 2.2 of the spec


    HTTP/1.1 defines the sequence CR LF as the
end-of-line marker for
    all protocol elements except the entity-body

but with the suggestion in 19.3 that

    Clients SHOULD be tolerant in parsing the
Status-Line and servers
    tolerant when parsing the Request-Line. In
particular, they SHOULD
    accept any amount of SP or HT characters between
fields, even
    though only a single SP is required.

    The line terminator for message-header fields is
the sequence
    CRLF. However, we recommend that applications, when
parsing such
    headers, recognize a single LF as a line terminator
and ignore the
    leading CR.

This means that 1) the spec is not vague and 2) the Python
code works according to the spec.  So my suggestion is
to remove the comment about being "vague" from the spec.

A diff is attached.

There's no uploaded file!  You have to check the
checkbox labeled "Check to Upload & Attach File"
when you upload a file.

Please try again.

(This is a SourceForge annoyance that we can do
nothing about. :-( )
