Hmm I don't think really a special case. I think that works becuase
checkout is implemented as update too. Are people already using this if
so then I guess we should leave it that way.

I'm generally under the impression that people don't use non-recurssive
checkouts becuase they don't work right. Given that I think we probably
should feel free to change the interface without worrying too much about
breaking anyone. If they're using it, it's already broken anyway.

Don't like revert at all. Revert undoes local mods. Doesn't make much
sense to add it there. Really we don't have an operation at all that
corresponds.

I do think we need some way to remove a dir. People are going to ask
for it. What if you typo an "include" and end up with the wrong dir.
People will either have to throw away their working copy and recheckout
or start mucking with the entries file.

One of our strengths is the ability to morph a working copy into what
you want without starting over. I think not having such a command would
weaken that ability if we finally fix non-recurssive checkouts.

I do think release would be fine. The extra work to make it a more
general "throw away this wc" command would be minimal.

I know there was some other people opposed to include/exclude that
haven't piped up yet. Would update/release satisfy those people? If so
I'm okay with that UI design.

Yeah but we don't really have a way to know what the server supports.
The server will not error out if we just add the fields and it doesn't
support it. It'll simply return all the extra data.

I think that the link_path trick might be a nice fall back but I don't
see the way to properly identify when to fall back until you're already
receiving extra data. In some cases you'd be better off to cancel and
start over and in others not, but then we run into the issue with neon
about not wanting to bail on a connection. *sigh*

That and I'm not really convinced that link_path will do what we want.
I kinda looked at it but didn't generate a bogus request to see if it
would actually work. Given the above I'm not sure it's worth it.
