+       Tune by using memchr and memrchr.
+       * doc.c (Fsnarf_documentation):
+       * fileio.c (Fsubstitute_in_file_name):
+       * search.c (find_newline, scan_newline):
+       * xdisp.c (pos_visible_p, display_count_lines):
+       Use memchr and memrchr rather than scanning byte-by-byte.
+       * search.c (find_newline): Rename from scan_buffer.
+       Omit first arg TARGET, as it's always '\n'.  All callers changed.
+
        Clean up read_key_sequence a tiny bit more.
        * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
        (read_key_sequence): Remove unused locals.
