    Add expandfmt_fun option for io:setopts

    Programmer have control for overriding expand-on-tab
    line input behavior. In addition to that, it would be
    useful to override default function for formatting
    tab-expanded results.

    Correct JCL's help indentation

    "q" command was not properly indented. Also, when
    erlang is not started in distributed mode, disable
    "r" command.

    Handle JCL's "r" command error when no pool started

    JCL's "r" command without parameters tries to run a
    remote shell on the one of pool's nodes. If the pool
    is not started, an error occurs, leading to unusable
    erlang console.
