recursion in ensure_uniform_revisions

Hi All,

Just wanted to check something with you all. ensure_uniform_revision currently
recurses into subdirs to make them all uniform. As part of implementing
update --nonrecursive, I needed to add a recurse member to edit_baton, so that
it wouldn't always run recursively. Then I realized that in close_directory,
we already schedule the revisions to be bumped, so I thought that maybe
ensure_uniform_revision never needs to be recursive.

Anyone with more knowledge of revision bumping care to comment?
