Re: Sparse directories unbackwardly compatible over ra_dav

This patch is functionally solid.

Initializing depth to svn_depth_infinity (instead of
svn_depth_unknown) would achieve nearly the same behavior, but
wouldn't handle the case where the client did send svn_depth_unknown
over the wire. I'm +1 on this patch.

Nitpick: Extraneous whitespace above the line starting with
"if (!saw_depth && ..."
