no need to create a var - lets just return the status var itself.

The section that describes how to work with timeouts was
misleading and could easily trick users to use the wrong API.

c-ares has had its own URL for a while and we should point
people to that. It also works with IPv6 since a long time.

curl_multi_timeout(3) is simply the wrong function to use
if you're using the multi_socket API and this document now
states this pretty clearly to help guiding users.

I've done this blindly, and the last piece that works with ares
should possibly be done differently now that c-ares isn't a
subtree within the curl tree anymore...

Prefixing the FTP quote commands with an asterisk really only
worked for the postquote actions. This is now fixed and test case
227 has been extended to verify.

Matt Wixson found and fixed a bug in the SCP/SFTP area where the
code treated a 0 return code from libssh2 to be the same as
EAGAIN while in reality it isn't. The problem caused a hang in
SFTP transfers from a MessageWay server.

using int is not fine on 64bit systems

strlen() returns size_t, but ssh libraries are wanting 'unsigned int'.  Add
explicit casts and use _ex versions of the ssh library calls.

Use ssize_t instead of int for the Curl_smtp_escape_eob nread
argument.

If you pass a URL to pop3 that does not contain a message ID as
part of the URL, it will currently ask for 'INBOX' which just
causes the pop3 server to return an error.

The change makes libcurl treat en empty message ID as a request
for LIST (list of pop3 message IDs).  User's code could then
parse this and download individual messages as desired.

My first instinct was to run the test script within the checked out
repository.  This small change to the script allows that to work as
expected.

Ben Greear brought a patch that from now on allows all protocols
to specify name and user within the URL, in the same manner HTTP
and FTP have been allowed to in the past - although far from all
of the libcurl supported protocols actually have that feature in
their URL definition spec.
