Rusty Russell 73ba5acca9 doc: fix flaw in escape transactions. ...

As reported by mmeijeri on r/Bitcoin:

As the signature doesn't cover the input itself, you could replace the
secret key from the escape transaction with 0, and it will use the "A and B"
branch of the output.

(This also fixes a bug in the anchor output where the OP_IF consumed the
secret).
