Query forwarding

picking up on this two-year-old message, trying to improve the
documentation of "foward-first":

>     forward-first: <yes or no>
>            If enabled, a query is attempted without the forward clause if
>            it fails.  The data could not be retrieved and would have caused
>            SERVFAIL because the servers are unreachable, instead it is
>            tried without this clause.  The default is no.

It seems this hasn't changed or improved since.  Based on the replies,
let me suggest a replacement:

forward-first: <yes or no>
  If a forwarded query is met with a SERVFAIL error, and this option
  is enabled, unbound will fall back to normal recursive resolution
  for this query as if no query forwarding had been specified.  The
  default is "no".
