EC2-ssh: looks like "\r" is not handled correctly?

[yarikoptic]

Running via reproman login on EC2 under screen session.

When attached to the screen (but not when just reattaching to see what was "logged" before) lines are broken (may be at original width?) and progressbars seems to create new lines instead of just overwriting an existing one:

and/or may be ANSI characters? (we need to make sure that we do not do any decoding from bytes and write them out as bytes as we get them). When I run TERM=screen glances outside the screen session -- seems to be all ok'ish. When inside screen -- garbles: indentations aren't right etc.
