Hmm.  If we don't have a tty, should we use anything?

Actually, I think environment variables fit the bill rather well.  You
can use them like options or as global settings, and I'm sure you can
arrange to have EMACS set BZR_PROGRESS="dot" -- I mean,
BZR_PROGRESS="bar" for you.  That would allow you to override it in the
one case you want it overridden.
