Noting of course taht there is also a lisp version of 'ls', which
provides this functionality on non-unix like platforms and provides some
additional functionality on platforms that do have a shell based 'ls'. 

My guess is that by forcing the -l switch, you get a fairly standard and
easy to parse output, making the code easier to maintain. Without -l,
you have to have more code to handle the parsing of the output and
possibly even more problematic, more code to handle the display and
movement within that display etc.
