Yes and no. But if progress bar yet don't print anything? If you run 
some fast operation, per example:

bzr init a
cd a
echo spam > spam
bzr add
bzr diff 2>stderr

And then see to stderr file you'll see file full of spaces and '\r' and 
no actual progress bar.

So I talk actually about situation when progress bar yet not printed 
(first seconds). This is very new improvement introduced by Aaron. And 
it great. But incomplete.
