Log message:
	2004-05-02  Paolo Carlini  <pcarlini@suse.de>
	
	PR libstdc++/15002 (continued)
	* include/bits/istream.tcc (getline(basic_istream<>&,
	basic_string<>&, _CharT)): Use a temporary buffer, thus
	avoiding reallocation for common case.
	
	* include/bits/istream.tcc (getline(basic_istream<>&,
	basic_string<>&, _CharT)): Change to use sgetc()/snextc() instead
	of sbumpc(), consistently with the other functions, thus also
	dealing correctly with the case of exceeded string::max_size().
