I seem to like replying to myself... I found one minor issue with the
patch, in the MANUAL file, I gave the incorrect syntax for the
--noproxy option. Where I said:
        curl --noproxy=localhost,get.this -x my-proxy:888 http://www.get.this/
I should have said:
        curl --noproxy localhost,get.this -x my-proxy:888 http://www.get.this/

I have also added the noproxy option to the man page.
