Clarify the mapping of files to queenside Author: @nickpelling We replace in the code the obscure expressions mapping files ABCDEFGH to ABCDDCBA by an explicite call to an auxiliary function : old: f = min(f, ~f) new: f = map_to_queenside(f) We used the Golbolt web site (https://godbolt.org) to find the optimal code for the auxiliary function.
