[BUG] progress bar with bzr pull/copy/copy_to

[Brian M. Carlson]

Sorry for all the mails, but Debian has ingrained in me the importance
of "one bug, one report".

When doing a bzr pull, the progress bar is updated.  When doing the copy
step, it shows total number of items copied, then, it flickers to
copy_to, which shows 0/1 items copied. Then it goes back, lather, rinse,
repeat.

My question is, wouldn't it make more sense to buffer some small amount
of items and then copy them?  I know it is probably more efficient
writing to disk (and will most likely get them less fragmented, and
therefore more efficient future access).  If we allow copying from one
remote repository to another, then it makes even more sense, because
there is less overhead.

If for some reason this is not possible or not desirable, could the
progress bar not flicker back and forth, as this is somewhat
disconcerting?
