True.  Can't do that using ls to generate the list of filenames as there
is no option to generate a null-separated list amongst ls's
multitudinous collection.

Go and read the xargs(1) man page carefully.  xargs is specifically
designed to avoid arglist overflows.

In this case, if you're going to call rm repeatedly with only one arg,
then xargs is pretty pointless.  You might as well do:

   find . -type f -depth 1 -exec rm -f '{}' ';'

but let's not leave people in any doubt that this is not the best option.=
