added info about my current idea about option separation between URLs on

   http://curl.haxx.se/mail/archive-2003-11/0091.html (Kevin Roth suggested)

 * Provide a way to make options bound to a specific URL among several on the

   command line. Possibly by adding a new option that separates options

   between URLs, similar to this:

   command line. Possibly by letting ':' separate options between URLs,

   similar to this:

      curl --data foo --url url.com --optionseparator

           --url url2.com --optionseparator \

      curl --data foo --url url.com :

          --url url2.com : \

          --url url3.com --data foo3

   (--optionseparator used to show my point, it would need a better name)

   (More details: http://curl.haxx.se/mail/archive-2004-07/0133.html)

   The example would do a POST-GET-POST combination on a single command line.
