This commit changes the ra_svn protocols, but not the other protocols.
Okay.

Err, shouldn't this be

  +                url:string ? text-deltas:bool ? depth:word 
  +                ? send_copyfrom_param:bool )

since clients before-your-change don't send the send_copyfrom_args param?

And here you removed an empty line?  Can we have it back please?

(that way one can use paragraph-motion commands (e.g., '}') when reading
the source.)

Shouldn't be committed.  (There are a few others in the diff.)

Is this ### still outstanding?

Should this be
  +      SVN_ERR(svn_ra_svn_parse_tuple(params, pool, "(?r)cbbcb?w?B",
?

Have you tested a server with this patch against a client before the patch?
(and vice-versa)

Daniel,

Sorry for the delayed response. I've committed the patch with your
suggestions in r990790. Below is just ACK's for those changes.

only ran the testsuite over ra_local.
