I welcome all the hard work put and the progress bar is nice in
situations where it fits. I assume many pof the developers here use
remote connections to exchange data in bzr project etc.

But, remember that there is crowd out there, who do not participate on
projects / need remote projects, where this progress bar may be nice.
The mass uses VCS tool to manage local things, even in companies.

The current problems:

- Check in's for small files is fast ("flickers", no need for progress bar)
- It breaks pipes and sane error handling ("grepping results")
- It doesn't work on slow modem connections ("takes bandwidth")
- It doesn't work on internal shells ("Emacs: M-x shell")
- It is not good for 3rd party programs that build in top of "bzr"
  (in programs using pipes or Emacs modes that use "process launches")

The benefits:

- On remote connections the progress is shown
- On big files the progress is shown

It really, really should not be on by default.

I understand that tool should be ready to use as it is installed, but
I believe the progress bar is more "convenience feature" than a
necessity and therefore it should be "extra" and "tunred on on
depand".
