Comment 1 for bug 920405

This affects all URLS that contain "&".

We use the get_query_url() function, which is designed to produce an escaped URI for use in HTML.

Since we use this as a redirect, we need an absolute and unescaped URI.

Perhaps something like

rawurlencode(WT_SERVER_NAME.WT_SCRIPT_PATH.WT_SCRIPT_NAME.$_SERVER['QUERY_STRING']);

We generate these links in (at least) two places. login_link() and WT_Controller_Base.
