I wrote a bug about the edit_p problem. I think there is a redirect in the process that loses the form variable because the form is submitted with a POST and the redirect is a GET. The big question is what to do about it. The redirect could pick up the form variables and export them on the URL or the form could be changed to a get. There is also a function that builds the URL in the first place. It could be changed to return the correct URL in the first place.
