I've just spent what seems like 10 minutes hunting around for the "Register Branch" link to do exactly this, and Launchpad has "helpfully" removed it and not told anyone (thanks Launchpad).
I'm creating a fresh branch of the trunk code -- when this is done, I should be able to cherry-pick the relevant commits from it and push those into a separate new branch.
No worries, I'll split this up.
