Fixed in r1334244.

Right. That was always the design plan.

> An important point here is that, by knowing the list of children, the semantics of the WC "incomplete" status can be greatly simplified.  We will only ever need to make new children "incomplete", never the directory itself.  Now the "incomplete" status will only need to mean, "We know there is a node with this name; we know nothing else about it".  It will no longer ever need to mean "This directory has some children which are completely (or partially?) fleshed out, and/or perhaps some that we don't know anything about yet".

Sure. That's why the wc_db interface and why the Ev2 add_directory API
requires the set of children up front. I just missed doing the same
for alter_directory. We're good now!

As a concrete example/improvement: during a checkout/update, a new
directory is "done" immediately. If the update stops, and is
restarted: you don't have to ask about the directory and its set of
children. *Just* the subset of children which are still incomplete.
