I think you either need to set PATH_INFO here *or* to avoid setting
SCRIPT_NAME.  CGit uses SCRIPT_NAME to decide whether to use path URLs
or the "url=" query parameter.  If it's using path URLs then you need to
have PATH_INFO specified as the full path (which must start with
$SCRIPT_NAME).

Note that I've never used fcgiwrapper so I don't know whether it will
set either of those automatically; I'm just going on how CGit behaves.
