| Note that when '-s' is combined with '-1', the 'total' is _not_ printed.
It is more complex than that (though that is correct, and applies when the
-1 is explicit, or when it is used because output is not to a tty).
ls has 5 output formats, -C -1 -l -m and -x
The "total:" header line is only printed in -C (the default for output
to a terminal, and only with -s), -x (also only with -s), and -l (traditional
long format, when it is almost always printed). The other 2 formats -1
(the default when output is not a terminal) and -m never print the total
header, with or without -s.
-C and -x are weird, (-x is just -C transposed), and if they actually print
multiple columns, they will also print the totals header. If only 1 column
is possible (if the line width isn't wide enough for more) then they transform
into -1, and don't print the totals (which they only ever print with -s).
That could perhaps be considered a bug - which would be trivial to fix.
Absurdly trivial for -x (just move a couple of lines), not much harder
for -C (insert a couple of lines).
