Progress should override output

[Wernight]

Currently outputs with --progress look like:
2.6GB 00:29:40 [1.6MB/s] [==========> ] 26% ETA 1h 21min
2.6GB 00:29:43 [1.6MB/s] [==========> ] 26% ETA 1h 21min
2.6GB 00:29:46 [1.4MB/s] [==========> ] 26% ETA 1h 21min

2.7GB 00:30:35 [1.4MB/s] [==========> ] 27% ETA 1h 20min
2.7GB 00:30:38 [1.4MB/s] [===========> ] 27% ETA 1h 20min
2.7GB 00:30:41 [1.5MB/s] [===========> ] 27% ETA 1h 20min

It could easily just update that line. There are two simple ways to do that (in Python):

import sys
from time import sleep

# '\r': Simpler way, having issue when console width is too small and output gets wrapped.
for i in range(0, 101, 5):
    sys.stdout.write("Download progress: {}% \r".format(i))
    sys.stdout.flush()

    # Do work here...
    sleep(0.1)
sys.stdout.write('\n')

# '\b': Better way
sys.stdout.write("Download progress: ")
for i in range(0, 101, 5):
    s = '%d%%' % i
    sys.stdout.write(s)

    # Do work here...
    sleep(0.1)

    sys.stdout.write('\b' * len(s))
sys.stdout.write('\n')
