remove blank line between function and it's description - remove the blank line between the declaration of the function and it's comment, leads to better IDE support when hovering over a function to see it's description - remove the unnecessary duplication of the function name in the functions description - slightly refactored code for lsb, msb in bitboard.h There are still a few things we can be improved later on, move the description of a function where it was declared (instead of implemented) and add descriptions to functions which are behind macros ifdefs closes https://github.com/official-stockfish/Stockfish/pull/4840 No functional change
