Yeah. How about adding something like this to the "Usage notes for
numeric formatting" between tables 9-26 and 9-27:
* The pattern characters S, L, D, and G represent the sign,
currency symbol, decimal point, and thousands separator characters
defined by the current locale (see lc_monetary and lc_numeric).
The pattern characters period and comma represent those exact
characters, with the meanings of decimal point and thousands
separator, regardless of locale.
