[Bug] the "getnum" operation does not work correctly in the de_DE.UTF-8 locale

[Erik Auerswald]

Hi,

the "getnum" operation does not work correctly in the de_DE.UTF-8
locale:

    $ locale | grep -e ALL -e NUMERIC
    LC_NUMERIC=de_DE.UTF-8
    LC_ALL=
    $ echo bar-1.2soom | env LC_ALL=C ./datamash getnum 1
    1.2
    $ echo bar-1.2soom | ./datamash getnum 1
    1
    $ echo bar-1,2soom | ./datamash getnum 1
    1

Thanks,
Erik
