A look of `./x` that is not there is a miss, as `x` and `/abs/x` are: the write answered, the err logged, not ENOENT

`./x` and `../x` failed their write with ENOENT while every other name
that opens nothing was a miss the write was still answered with. They
are misses now too, said and logged `look: ./x: no such file`. A pane's
own directory gone stays a failure.
