No, I don't think you're missing anything -- I think I was a bit too
rigid about always replacing 'recurse' booleans with svn_depth_t
'depth' parameters. In this case, it would have been better to just
get rid of the parameter entirely.

I'll take care of this as soon as I commit up my current set of
changes, which is about creating the svn_wc_get_status_editor3() API.
(In that case, I think simply replacing 'recurse' with 'depth' is the
right course, but note that it will be svn_depth_unknown when the user
didn't pass an explicit depth, because then it just crawls whatever
working copy depths it finds.)

Peter, thanks for the review! It helps a lot to know you're watching.
