Use -1 for CHAR_MAX instead of empty string as recommended by POSIX
Still not parsed in localeconv() in anycase

Replace "3;3" with "3". This is cosmetique, all integer before \0 (i.e. \3)
repeated forever according to SUSv2

Remove "0;0" - \0 means not "no grouping" but repeat forever previous char,
and added automatically. Empty string could be parsed later into CHAR_MAX
(real "no grouping") by localeconv()

Repeat after me: no commits when tired.

Add the correct named file for LC_NUMERIC for nl_NL locales.
