Make `ls` list files in multiple columns

[waits]

It would be nice if the ls command listed files in columns so more can fit on a screen. Most/all unix-based ls commands do this, for example:

$ ls /etc/alphabet
alpha  charlie  echo     golf   india
bravo  delta    foxtrot  hotel  juliett

$ ls /srv/random-rails-app
app  config     db       Gemfile.lock  log     Rakefile  tmp
bin  config.ru  Gemfile  lib           public  test      vendor

Whereas this tool's output is:

$ dbxcli ls /some-folder
alpha
bravo
charlie
delta
...

The output of the --long option would of course remain unchanged.
