c-common.c (time_char_table): Mark up formats added in C99 and make other corrections.

	* c-common.c (time_char_table): Mark up formats added in C99 and
	make other corrections.  %D and %g were added in C99.  %Og is an
	extension.  %EX is permitted.  %R, %T, %n, %r, %t were added in
	C99.  %e was added in C99.  %Oj is an extension.  %G and %z are in
	C99 rather than GNU extensions, but %OG and %Oz are extensions.
	%h was added in C99.  %C was added in C99.  %OY and %OC are
	extensions.  Add the C99 format %F.
	(check_format_info): If pedantic and not in C99 mode, warn for C99
	formats, %E and %O.
