There was a logic error in a formula, reported by Atsushi Torokoshi. Ashutosh Bapat furthermore recommended to change notation for a variable that was re-using a letter from a previous formula, though his proposed patch contained a small error in attributing what the new letter is for. Also, instead of his proposed d' I ended up using e, to avoid confusing the reader with quotes which are used differently in the explaining prose. Bugs appeared in commit 2686ee1b7ccfb9214064d4d2a98ea77382880306.
