You may be misunderstanding the glibc format of the grouping information
returned by the nl_langinfo function. As you can see
  - from glibc/stdio-common/printf_fp.c, function __guess_grouping,
  - from glibc/stdio-common/vfprintf.c, function group_number,
when the first value in the array is zero or negative or 127, it means
"no grouping should be done".

The POSIX description of 'grouping' for localeconv() [1] and the description in
glibc's manual [2] don't mention negative numbers, but yes, sometimes you need
to look into the source code to understand glibc specific details.
