commit-reach: reduce requirements for remove_redundant()
Remove a comment at the beggining of remove_redundant() that mentions a reordering of the input array to have the initial segment be the independent commits and the final segment be the redundant commits. While this behavior is followed in remove_redundant(), no callers rely on that behavior. Remove the final loop that copies this final segment and update the comment to match the new behavior.
