You don't understand *how* "the underscore is used for spacing".


The underscore indicates that enough space for the character that
follows it is to be inserted. So the width of the - sign *is* the amount
of space to be inserted.

If you wanted the width of the underscore inserted, you' use two of them.

used for spacing but I'm still unclear as to what the purpose of the
trailing minus sign is - it doesn't seem to do anything..?
