    Updated miller to 4.5.0.

    4.5.0

    Customizable output format for redirected output

    In a natural follow-on to the 4.4.0 redirected-output feature, the
    4.5.0 release allows your tap-files to be in a different output
    format from the main program output.

    For example, using

    mlr --icsv --opprint ... then put --ojson 'tee > "mytap-".$a.".dat",
    $*' then ...

    the input is CSV, the output is pretty-print tabular, but the
    tee-files output is written in JSON format. Likewise --ofs, --ors,
    --ops, --jvstack, and all other output-formatting options from the
    main help at mlr -h and/or man mlr default to the main command-line
    options, and may be overridden with flags supplied to mlr put and
    mlr tee.

    4.4.0

    Redirected output, row-value shift, and other features

    The principal feature of Miller 4.4.0 is redirected output. Inspired
    by awk, Miller lets you tap/tee your data as it's processed, run
    output through subordinate processes such as gzip and jq, split a
    single file into multiple files per an account-ID column, and so
    on.

    Details:
    http://johnkerl.org/miller/doc/reference.html#Redirected-output_statements_for_put

    Other features:

        mlr step -a shift allows you to place the previous record's
        values alongside the current record's values:
        http://johnkerl.org/miller/doc/reference.html#step

        mlr head, when used without the group-by flag (-g), stops after
        the specified number of records has been output. For example,
        even with a multi-gigabyte data file, mlr head -n 10 hugefile.dat
        will complete quickly after producing the first ten records
        from the file.

        The sec2gmtdate verb, and sec2gmtdate function for filter/put,
        is new: please see
        http://johnkerl.org/miller/doc/reference.html#sec2gmtdate and
        http://johnkerl.org/miller/doc/reference.html#Functions_for_filter_and_put.

        sec2gmt and sec2gmtdate both leave non-numbers as-is, rather
        than formatting them as (error). This is particularly relevant
        for formatting nullable epoch-seconds columns in SQL-table
        output: if a column value is NULL then after sec2gmt or
        sec2gmtdate it will still be NULL.

        The dot operator has been universalized to work with any data
        type and produce a string. For example, if the field n has
        integers, then instead of typing mlr put '$name = "value:".string($n)'
        you can now simply domlr put '$name = "value:".$n'. This is
        particularly timely for creating filenames for redirected
        print/dump/tee/emit output.

        The online documents now have a copy of the Miller manpage:
        http://johnkerl.org/miller/doc/manpage.html

        Bugfix: inside filter/put, $x=="" was distinct from isempty($x).
        This was nonsensical; now both are the same.
