Strange.  It says it's stacking why I try, but then there's no stacked
config at the end:

$ bzr init lp:~abentley/bzrtools/stack-test
Using default stacking branch /+branch-id/8633 at
bzr+ssh://bazaar.launchpad.net/~abentley/bzrtools/
Created a standalone branch (format: unnamed)

python -c 'from bzrlib.branch import Branch; print
Branch.open("bzr+ssh://bazaar.launchpad.net/~abentley/bzrtools/stack-test").get_stacked_on_url()'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/bzrlib/remote.py", line 3509,
in get_stacked_on_url

    raise translator(err, find, get_path)
bzrlib.errors.NotStacked: The branch
'RemoteBranch(bzr+ssh://bazaar.launchpad.net/~abentley/bzrtools/stack-test/)'
is not stacked.
