Just because yum is interactive doesn't mean it shouldn't handle
screen wrapping properly. Notice how `ls` (at least on my system)
shows the results in columns with colours, but when you pipe it, it
automatically outputs as a list without colours. I think this is to do
with detecting the usage of /dev/tty or something (I can't remember).
If python is not capable of doing that kind of thing I would be
surprised.
