Comment:

 (In [5461]) On pass (from vcl_recv) we did not remove the backends
 Content-Length
 header before adding our own.

 We can not do this with the fetch filtering, because pass might send
 HEAD requests to the backend.

 XXX: It's arguable that the filtering stuff might be better done
 inline than with a table.

 Fixes: #801
