It does that only when stdout is a tty. The output in this mode has
been improved recently. Here's what I get:
% ls
's,7,big'$'\n''improvements'$'\n''in'$'\n''code'$'\n'
% ls | cat
s,7,big

That's just the output of `ls` when stdout is a tty.

This time stdout of `ls` is not a tty, so it prints the file name
verbatim. After that your code splits the output on IFS and joins it
back together with spaces. It's WAI.
