	Already fixed yesterday.  It's not link_path_walk(), it's handle_dots()
ignoring an error returned by step_into().

commit 5e3c3570ec97 is the broken one; commit 20971012f63e is its variant with the
fix folded in.  So next-20200325 has the bug and next-20200326 should have it
fixed.  Could you check the current -next and see if you still observe that crap?
