Add the necessary magic to make the thousands separator work for
floating-point formats in the Greek locale. This allows printing
numbers with the ' format modifier, like this:

$ env -i LC_NUMERIC=el_GR.ISO8859-7 printf "%'.3f\n" 1024000
1.024.000,000

Back out my "3;3" -> something change. While technikally the same, it only
leads to confusion.

el_GR: change "0;0" to "-1".
"0" is repeater for previous number, not no grouping

Add LC_NUMERIC, LC_MESSAGES and LC_MONETARY for el_GR.ISO_8859-7
