Comment 3 for bug 318214

When the user enters a source location, the destination location should change to reflect it, provided the source isn't relative. For example:

1. source=lp:qbzr should suggest qbzr
2. source=trunk should suggest nothing.

As a nice bit of dwim, source=lp:bzr-xxx should suggest xxx.

I'd really like to see this done soon. See https://lists.launchpad.net/bzr-doc/msg00005.html.
