In what way am I "using" that format? I'm not specifying any format in
any of the commands I use. (Please check the session log I posted
earlier in the thread.)

If I'm not specifying a format in any of the commands in the session,
how can I "not use" a specific format? Should bzr not be choosing the
right format (or at least one that won't be *wrong*) if I don't
specify?
