[patch/ob] Add _DATE_FMT for nl_langinfo

[Corinna Vinschen]

Hi,

I applied the below patch as obvious.  There was no way to access the
lc_time_T member date_fmt.  The GNU C library defines an nl_time
_DATE_FMT to access this member, and it is used in coreutils' date(1)
application if available.


Corinna


	* libc/include/langinfo.h (_NL_TIME_DATE_FMT): Define new nl_item
	value for LC_TIME entry date_fmt.
	(_DATE_FMT): Define "official" GNU name same as _NL_TIME_DATE_FMT.
	* libc/locale/nl_langinfo.c (nl_langinfo): Add case for _DATE_FMT.
