You can use the set python of scripts descibed in the wiki here:
http://wiki.openstreetmap.org/wiki/Upload.py to do this to some
degree.  The "smarter-sort" script sorts your changes in such a way
that they look as much as possible like a manual edit.  This way
objects and their chilren hopfully end up in an atomic diff.
