pull/init from bzr merge directive

[Brian de Alwis]

To create the merge directive:

# bzr send requires a submit branch to provide info on what is known on the other side
# i.e., to decide what commits need to be in the merge directive.  We want everything,
# so we specify an empty branch.  Is there no location-alias for an empty branch?
$ bzr init /tmp/empty
$ bzr send --no-patch -o /tmp/backup.bundle /tmp/empty

To restore the merge directive:
$ cd new/root
$ bzr init
$ bzr pull /tmp/backup.bundle
