When printing one name per line and not sorting, ls now uses
constant memory per directory, no matter how many files are in
the directory.
* ls.c (print_dir): Print each file name immediately, when possible.
* NEWS: Mention the improvement.
join has significantly better performance due to better memory management
+ ls now uses constant memory when not sorting and using one_per_line format,
+ no matter how many files are in a given directory
+
od now aligns fields across lines when printing multiple -t
specifiers, and no longer prints fields that resulted entirely from
padding the input out to the least common multiple width.
