It works perfectly fine here. GNU Emacs 21.4.1.

In the past, when there was special code to disable the progress bars in
the Emacs shell, I actually needed to make emacs lie and pretend that
TERM was something "xterm" instead of "dumb".

IMHO, disabling progress bars by default everywhere would be bong, they
are usually useful information (although they certainly could be finer
grained and more expressive in some places), and it's only desirable to
disable them in special cases.

On the other hand, I would not object to:

 * not displaying a progress bare during the first two seconds, that
should be short enough for the user not to start worrying.

 * doing a better job of limiting the rate of updates and being more
efficient with bandwidth.
