Many thanks. So here is what I did. I registered a branch set_trace, then I did:

$ bzr launchpad-login ondrej-certik

and setup my ssh keys. Then I did:

$ bzr push lp:~ipython-dev/ipython/set_trace
bzr: ERROR: Target directory lp:~ipython-dev/ipython/set_trace already
exists, but does not have a valid .bzr directory. Supply
--use-existing-dir to push there anyway.


so I tried the --use-existing-dir options, is that the correct way?

$ bzr push --use-existing-dir  lp:~ipython-dev/ipython/set_trace
Using default stacking branch /~ipython-dev/ipython/trunk at
bzr+ssh://bazaar.launchpad.net/%7Eipython-dev/ipython/
Created new branch.

then I went to the web address of the branch:

https://code.edge.launchpad.net/~ipython-dev/ipython/set_trace

and clicked "Propose for merging into another branch":

https://code.edge.launchpad.net/~ipython-dev/ipython/set_trace/+merge/8855

let me know if I did things correctly.

If I want to checkout the trunk branch instead (e.g. without my
commit), how do I do that? E.g. the equivalent of:

git checkout master
git checkout my_branch

looking here:

it's seems pretty complex. I am new to bzr, so I might be doing things
the wrong way.
