It is not a matter of listing commands, but effects. `push' is not
forbidden to work in general. But if certain `push' operation has the
effect of removing revisions from the left hand of the DAG (moving them
to some other place of the DAG, in this case) it is not accepted. A
`push' that just appends revisions is fine.

As `bzr uncommit' always removes revisions from the left hand of the
DAG, it always is rejected.
