So, what you actually want is '--partial-recurse' or '--max-depth=1'. Because
you want to give a directory, and get the values for all children, but not for
their children.

If you knew all the entries, you could do:

tree.iter_changes(specific_files=[names, for, all the files, in the directory], r)

That doesn't help you much for missing files, and any directories you supply
will be recursively searched.

It isn't particularly hard to do what you want, we just haven't had a specific
use case for it, and thus haven't implemented it. WT4.iter_changes() in
particular is rather crufty in deference to performance. I've certainly
considered rewriting it to be more 'obvious', and just create a pyrex/C
extension as the optimized form.
