New description:
Because of either a readline or a Python bug, sometimes control characters
are output by Python. For example, on my Gentoo Linux system:
{{{
jdemeyer@arcanis:~$ sage --python -c 'import readline' |cat -t
^[[?1034hjdemeyer@arcanis:~$
}}}
This breaks doctests at #12249 for `sage-run`. The easiest solution is to
unset the `TERM` environment variable when running `sage-run` or `sage-
eval`. This will effectively disable readline.
