- AbstractRequest#parameters destructively overwrites request_ and query_parameters

Hi guys,

I'm looking for some +1's for a bug fix patch I submitted:http://
dev.rubyonrails.org/ticket/9949

AbstractRequest#parameters is overwriting request_parameters when
called, so I drew up a patch and test case to fix it. Any people
willing to try it out would be much appreciated.

Thank,
Scott Fleckenstein
