I also agree. While there is a use case there, it's fraught with
unclean edges and hard-to-explain consequences. Better for us to keep
it simple: if people want to pick and choose among entries, that's
what a depth-0 parent directory is for.
So, it looks like I'm going to have some time to work on this. I'll
start by checking the design doc into notes/. I'm talking about the
writeup posted by Eric Gillespie, here:

Subject: [PROPOSAL] Incomplete working copies (issue #695)
Date: Thu, 22 Jun 2006 22:35:06 -0700
Message-ID: <25668.1151040906@gould.diplodocus.org>
...and will make a note in issue #695, of course.
I think the work can happen in trunk, but I'll create a branch if it
looks like it's going to be destabilizing.
Note that this proposal is similar to what Ben Reser came up with long
before (http://svn.haxx.se/dev/archive-2005-07/0398.shtml, and thanks
to Eric for digging up that URL). The main difference is that the new
proposal doesn't involve adding any new subcommands, and that the
depth flag gives us, I think, somewhat greater flexibility in where we
take this feature in the future. Nevertheless, Ben has done some of
the hard thinking already, especially about how to tweak the update
reporter, and that's going to help a lot.
Anyway, just a heads up that this will actually be happening. Looking
forward to the reviews!
