Handling of query string in manifest media URLs

Media URLs in the manifest can contain query string (called "auth" here), e.g. <media url="some?name=value" ...>. The fragment URLs then would be "...someSegX-FragY?name=value". Ideally, there should be a command-line switch for controlling this behavior, because I can easily imagine a situation where the segment and fragment numbers are passed via the query string, e.g. <media url="some?name=value&frag=" -> "...some?name=value&frag=SegX-FragY".
