Account for padding when wrapping lines

You can check for one-off errors with the following command:

    $ alias wash-colors="sed 's/\x1B\[[0-9;]\{1,\}[A-Za-z]//g'"
    $ ./4cli | head -n 3000 | wash-colors | grep ".\{81,\}"

It should only show lines with a very long word (e.g. links), and text
that is not printed by 'print_post_contents' (e.g. thread titles).
