shell doesn't update displayed info when switch branches

It affects me too. Shell will be very usefull when using colocated branches (by bzr-colo) if it doens't countain this bug.

For instance (it should work this way):

$ bzr colo-init colo-repo
$ cd colo-repo
$ bzr pull ..\trunk
$ bzr shell
bzr trunk:640$ colo-branch -r 300 fix1
bzr fix1:300$ ci -m "Fix for bug1"
bzr fix1:301$ switch trunk
bzr trunk:640$ merge colo:fix1
bzr trunk:640$ ci -m "Fix for bug1"
bzr trunk:641$

But now it looks like:

$ bzr shell
bzr trunk:640$ colo-branch -r 300 fix1
bzr trunk:640$ ci -m "Fix for bug1"
bzr trunk:640$ switch trunk
bzr trunk:640$ merge colo:fix1
bzr trunk:640$ ci -m "Fix for bug1"
bzr trunk:641$
