Indeed, I missed the importance of indenting subsequent lines, but a
quick glance at 'ls --help' shows that it is the right thing to do.

Optional arguments to short options cannot be separated by whitespace.

-e has an optional option-argument, so it must be written '-e[END]', not
'-e [END]'. That is, 'xargs -e/' is different than 'xargs -e /'.

-i is another argument with optional argument; it needs to be written
'-i[R]' to make it obvious.

And again, needs to be written '-l[MAX-LINES]'.
