Interesting that recording a <NEW_URL> is exposed as a side effect of pull.  What if I receive notification of a changed URL and want to act on that information before it slips my mind but am not ready to perform a pull?  Am I reduced to piercing the abstraction and editing .bzr/branch/branch.conf directly?

How will Explorer handle this use scenario?
