...and some very minor coding style policing.

...and some comment typos!

Added support for the automatic conversion of Unix newlines to CRLF
during mail uploads.

Feature: http://curl.haxx.se/bug/view.cgi?id=1456

and some minor edits

refer to functions with the man page section properly

Makes the example much easier and straight-forward!

This makes it much easier to run multiple tests in the same directory,
just altering the command lines used.

warning: variable 'connection_id' set but not used
warning: unused parameter 'lineno'

After commit 48d19acb the HTTP code would call Curl_nss_force_init()
twice when decoding a NTLM type-2 message, once directly and the other
through the call to Curl_sasl_decode_ntlm_type2_message().

In addition to NTLM, use Kerberos and SPNEGO as proxies to the crypto
feature.

...and converted tab characters, from commit 4b4e8a58, to spaces.

Such as !SSPI as we do for the NTLM and Digest tests.

Verifies the upgrade request, but gets a plain 1.1 response

This commit disables pipelining for HTTP/2 or upgraded connections.  For
HTTP/2, we do not support multiplexing.  In general, requests cannot be
pipelined in an upgraded connection, since it is now different protocol.
