FUNCTIONS
  column_run
    Usage:

     column_run(%args) -> [$status_code, $reason, $payload, \%result_meta]

    Run several commands and show their output in multiple columns.

    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
        (as well as allowing each command to have its unique arguments or
        environment variables).

    This function is not exported.

    Arguments ('*' denotes required arguments):

    *   args_arrays => *array[aos]*

        Arguments to give to each command (an array of arrays of strings).

        If "--common-args" is also set, then the common arguments will be
        added first, then the per-command arguments.

    *   commands* => *array[str]*

    *   common_args => *array[str]*

        Common arguments to pass to each command.

        If "--args-arrays" is also set, then the common arguments will be
        added first, then the per-command arguments.

    *   common_envs => *hash*

        Common environment variables to pass to each command.

    *   envs_arrays => *array[hos]*

        Environment variables to give to each command (an array of hashes of
        strings).

    *   linum_width => *posint*

        Line number width.

    *   on_long_line => *str* (default: "clip")

        What to do to long lines.

    *   separator => *str* (default: "|")

        Separator character between columns.

    *   show_linum => *bool*

        Show line number.

    Returns an enveloped result (an array).
