+ Fix to avoid a denial-of-service attack if the display width is
+ enormous. Also, clean up the code a bit by removing duplicate code.
+
+ * src/ls.c (init_column_info): Remove forward decl; no longer needed.
+ (calculate_columns): New function, that contains code that used
+ to be common to print_many_per_line and print_horizontal.
+ (print_many_per_line, print_horizontal): Use it.
+ (decode_switches): Set max_idx here, not in calculate_columns.
+ (print_current_files): Don't call init_column_info; calculate_columns
+ now does that.
+ (init_column_info): Don't allocate a lot more space than is needed
+ to represent the current set of files. Allocate all the new
+ size_t cells in one call to xnmalloc, rather than a row at a time.
