cpplex.c (_cpp_get_fresh_line): Revert my no-longer-needed 08-28 change...

	* cpplex.c (_cpp_get_fresh_line):  Revert my no-longer-needed
	08-28 change, since we're never called with a NULL buffer.
	(_cpp_lex_direct):  Likewise.
	* cpptrad.c (_cpp_read_logical_line_trad):  Likewise.
	Return false if buffer is NULL at end.

	* cpplex.c (_cpp_get_fresh_line):  Return value now just depends on
	whether pfile->buffer is NULL after pop, ignoring return_at_eof.
