Takes newline-separated items on stdin and prints them in columns on stdout.
columnize divides the items into the largest number of columns such that
none of the rows exceed a maximum text width (120). Each row item has a
minimum of 2 spaces padding between adjacent items.
columnize lays out text containing
ANSI color codes
as if the escape codes were invisible, so it's suitable for columnizing colored
outputs, such as from ls --color=always.
