I removed: "139 - Christopher Palow's CURLM_EASY_HANDLE_EXISTS patch" simply

because at the current point in time I think the benefit of adding that new
return code is very slim and it is a lot of work to introduce new return codes
(for docs and maintenance etc)

I added "145 - Phil Blundell's CURLOPT_SCOPE patch/work" since I want it
sorted/committed.
