14079 * cpphash.h (CPP_INCREMENT_LINE): New macro.
14080 (struct cpp_buffer): Moved fields saved_cur, saved_rlimit to ...

14100 (_cpp_get_fresh_line): Don't need to adjust line for missing newline.
14101 (_cpp_lex_direct): Use linemap_position_for_column.
14102 * c-ppoutput.c (maybe_print_line, print_line): Don't take map
