Route requirements ignore Regexp modifiers fix - comments please

I've created a patch that allows route requirements to use the Regexp IgnoreCase and Extended Syntax modifiers, so you can do things like:

map.connect 'country/:country_code', :controller => 'country',   :action => 'show',   :country_code => /GB|US|CA/i

The ticket and patch is at http://dev.rubyonrails.org/ticket/11421

Comments appreciated
