commit to empty master branch after local commits fails

[Martin Pool]

In a checkout of a local branch:

[0] mbp@grace% touch a
[0] mbp@grace% bzr add a
added a
[0] mbp@grace% bzr ci --local -m local
Committing revision 1 to "/tmp/co/".
added a
Committed revision 1.
[0] mbp@grace% bzr ci -m remote
bzr: ERROR: Bound branch BzrBranch6('file:///tmp/co/') is out of date with master branch BzrBranch6('file:///tmp/master/').
To commit to master branch, run update and then commit.
You can also pass --local to commit to continue working disconnected.
zsh: exit 3 bzr ci -m remote

this is like bug 120968, but distinct.
