'As for click_request_data, but returns a list of (key, value) pairs.
You can use this list as an argument to ClientForm.urlencode.  This is
usually only useful if you\'re using httplib or urllib rather than
urllib2 or ClientCookie.  It may also be useful if you want to manually
tweak the keys and/or values, but this should not be necessary.
Otherwise, use the click method.
Note that this method is only useful for forms of MIME type
x-www-form-urlencoded.  In particular, it does not return the
information required for file upload.  If you need file upload and are
not using urllib2, use click_request_data.
Also note that Python 2.0\'s urllib.urlencode is slightly broken: it
only accepts a mapping, not a sequence of pairs, as an argument.  This
messes up any ordering in the argument.  Use ClientForm.urlencode
instead.'
