Either way would work, as far as I am concerned. The purpose is to
inform the user that the context (partition) has changed. I have
a tiny preference towards having consistent output, if we can, with
commands executed from the prompt and commands executed from elsewhere
such as user-defined commands for instance. But that preference really
has no additional technical merit that I can think of, so I'm happy to
change the observer to use something triggered just before printing
the command prompt (btw: it does not matter in this case, but I believe
that the prompt also gets printed as "> " while entering a canned
sequence of command).
