I think this is ready to be merged to trunk, but there are two
outstanding issues that really need to be addressed before we release:

  * When the source of the copy is the repository, the current
    implementation can potentially open and close a zillion RA sessions.
    It does not even attempt to detect if they're sessions to the same
    repository, and consequently does not reuse sessions. A lot of work
    has been spent in reducing the number of RA sessions opened during
    an operation, so this is really unacceptable.

  * When the target is the working copy, the current implementation
    overrides the ignore-externals flag during the copy until the
    externals are pinned. However, no attempt is made to remember the
    original value of this flag. Also, I think there's a fundamental
    problem with the approach to pinning when the WC is the target: if
    the copy succeeds, but pinning the externals fails for whatever
    reason -- even a cancellation -- the working copy will be in an
    inconsistent state. IMO, the code should queue up WC work items for
    the actual pinning, so that the pinning can be rolled forward (or
    reverted) completely, not left in a half-baked state.
