Just try it, replace: (isearch-repeat 'forward arg))) by: (isearch-repeat (if isearch-forward 'forward 'backward) arg))) in isearch-beginning-of-buffer, type C-r isearch M-s M-<, and you'll see that on the contrary not changing the direction is unexpected, that behavior can only be considered as a bug. >> If you do not change the search direction after moving to BOB, the >> result is not what you would expect.
