Takes data on standard input or in any specified files and dumps it to
standard output similar to cat or cut.  However, all output will be
truncated to the current terminal width (according to `tput cols') to
prevent long output lines from wrapping.  This is very similar to
`cut -c1-\${COLUMNS}' but it should work better to interpret terminal
color attributes.
