/**
* _Py_InsertThousandsGrouping:
* @buffer: A pointer to the start of a string.
* @n_buffer: Number of characters in @buffer.
* @digits: A pointer to the digits we're reading from. If count
* is non-NULL, this is unused.
* @n_digits: The number of digits in the string, in which we want
* to put the grouping chars.
* @min_width: The minimum width of the digits in the output string.
* Output will be zero-padded on the left to fill.
* @grouping: see definition in localeconv().
* @thousands_sep: see definition in localeconv().
*
* There are 2 modes: counting and filling. If @buffer is NULL,
* we are in counting mode, else filling mode.
* If counting, the required buffer size is returned.
* If filling, we know the buffer will be large enough, so we don't
* need to pass in the buffer size.
* Inserts thousand grouping characters (as defined by grouping and
* thousands_sep) into the string between buffer and buffer+n_digits.
*
* Return value: 0 on error, else 1. Note that no error can occur if
* count is non-NULL.
*
* This name won't be used, the includer of this file should define
* it to be the actual function name, based on unicode or string.
*
* As closely as possible, this code mimics the logic in decimal.py's
_insert_thousands_sep().
