[The] practical question [is] how best to code into a shell script the
multiple options you cite above.
You don't really need to code in *all* the possibilities; you just
need to know whether the input is *empty*, not whether it's a
multi-message file, because formail works fine with the edge case of a
single-message file.
So something along the lines of
if test -s $INPUTFILENAME
then FORMAIL="formail -s"
# else FORMAIL=
fi
$FORMAIL procmail .... < $INPUTFILENAME
