Log message:
	2004-08-01  Paolo Carlini  <pcarlini@suse.de>
	
	PR libstdc++/12791
	* include/bits/locale_facets.tcc (time_get::_M_extract_num):
	Rewrite, stop the parsing as soon as a digit cannot possibly
	lead to a final number within the bounds; otherwise, simplify,
	avoiding __ctype.is() and atoi().
	
	* include/bits/locale_facets.tcc (time_get::_M_extract_via_format):
	Minor tweak: a 4-digit integer cannot be bigger than 9999.
