statichttprepo: don't send Range header when requesting entire file When requesting files using statichttprepo.httprangereader, a request for the entire file is sent with a Range: bytes=0- header. This causes problems with web servers such as Cherokee that return an HTTP 416 when an empty file is requested in this way, which in turn cause some repository clone attempts to fail. This patch omits the Range header when the entire file is being requested, which fixes the problem.
