=head3 humanize STRING [one_line]

Method that takes a STRING with control characters and makes it human
readable in such a way as to not do anything funky with the terminal.
If one_line is true, be more conservative about what we treat as
control character.

As above, but always be conservative, and replace with a '?' instead
of something more elaborate.
