Unspaced dashes are not dashes, they are hyphens. Someone has recently been changing the dashes to hyphens; I've changed some back but I haven't caught them all.

Double dashes are rarely used, and I have seen them corrected.

The single dash is often used, and of your three choices is the most correct, but there is a longer dash, that I don't know how to make, that is the preferred choice. Hopefully someone who knows how to make it will see this thread.
