The order of commands is not in sync between help page and manual, but
I refrained from reordering to avoid churn.


NB: On a 80x24 xterm, the help page is already using the last line,
hiding all of the "Hit any key to continue: " prompt except its first
five characters which land on the last `u [-user]' line.

With those two lines added, the `S' line becomes the last one but and
on a 80x24 terminal the continue prompt gets can be seen completely.

I guess this can be fixed/improved regardless of the last line, but
that's stuff for another diff.
