Yep, that's a pretty effective way to do it. One simple method to it
is to format the whole string as a single whole, then left justify it
in a field of (say) 79 characters, and output that:

msg = "Progress: %d%% (%d/%d)... %s" % (done*100/total, done, total,
current_file)
print msg.ljust(79)+"\r",
sys.stdout.flush()
