nfiles, files_index, tabsize, line_length, struct column_info.line_len,
struct column_info.col_arr[0], max_idx):
Now size_t, not int.
(get_funky_string): Return bool indicating success, instead of
a negative count to indicate failure. Store number of columns
through new parameter OUTPUT_COUNT; that way, they can never
go negative. Change equals_end from int to bool. All uses
changed.
(struct column_info.valid_len): Now bool, not int. All uses changed.
(dired_dump_obstack, get_funky_string, clear_files,
extract_dirs_from_files, print_current_files,
print_many_per_line, print_horizontal, init_column_info,
put_indicator, length_of_file_name_and_frills,
print_with_commas): Use size_t, not int, for local variables
that count sizes.
(decode_switches): Decode sizes using xstrtoul, not xstrtol.
Check for TIOCGWINSZ returing negative values (or values greater
than SIZE_MAX!).
(visit_dir, main, parse_ls_color, queue_directory, add_ignore_pattern,
init_column_info):
Use xmalloc and xnmalloc, not XMALLOC.
(gobble_file): Use xnrealloc, not XREALLOC.
(print_color_indicator): Remove now-unnecessary cast to size_t.
