does not work as expected. Replacing this with

               case "$(read yesno; echo $yesno)" in [Nn]*) exit 1 ;; esac

would work as intended, as Mikael has pointed out.
  Wouldn't it be more elegant to

	case "$(head -n 1)" in [Nn]*) exit 1 ;; esac
Only if head is a built-in, otherwise you fork needlessly.  Not that
this is a performance critical part, but I wouldn't call it "elegant".

What's wrong with the following variant, already used a few lines up in
the file?

	read yesno
	case "$yesno" in [Nn]*) exit 1 ;; esac
