/**
 * Derive push operation specification from this push operation result.

 * Specification is created basing on URIs of remote repositories in this
 * result that completed without connection errors, and remote ref updates
 * from push results.
 * <p>
 * This method is targeted to provide support for 2-stage push, where first
 * operation is dry run for user confirmation and second one is a real
 * operation.
 *
 * @param requireUnchanged
 *            if true, newly created copies of remote ref updates have
 *            expected old object id set to previously advertised ref value
 *            (remote ref won't be updated if it change in the mean time),
 *            if false, newly create copies of remote ref updates have
 *            expected object id set up as in this result source
 *            specification.
 * @return derived specification for another push operation.
 * @throws IOException
 *             when some previously locally available source ref is not
 *             available anymore, or some error occurred during creation
 *             locally tracking ref update.
