Isn't it rather just:

- dash escape nested -----BEGIN PGP MESSAGE----- (et al)
- dash escape From

I think the idea has always been to escape all dashes so that the receiver can indiscriminately remove the <dash><space> prefix from every line in a received message. It is precisely this approach which makes it possible to allow arbitrary sentences to be dash-escaped *without* the transformation being irreversible.
