    This utility is similar to using the Unix utility pr to columnate
    output, something like (in bash):

     % pr -T -m -w $COLUMNS <(command1 args...) <(command2 args...)

    except with the following differences:

    *   commands are run in sequence, not in parallel (although parallel
        execution is a TODO list item);

    *   all output are collected first, then displayed (although streaming
        output is a TODO list item);

    *   multiplexing STDIN to all commands;

    *   ANSI color and wide character handling;

    *   passing adjusted COLUMNS environment to commands so they can adjust
        output;

    *   passing common arguments and environment variables to all commands

* passing common arguments and environment variables to all commands (as well as
  allowing each command to have its unique arguments or environment variables).
