Subject: [PATCH] For all functions known to be infected by LC_NUMERIC, add
 short CAVEATS pointing to the new CAVEATS section in setlocale(3). Make those
 in wprintf(3) and wscanf(3) more concise since duplicate information is a bad
 idea. Incompleteness of information originally pointed out by millert@. OK
