bash(1) returns 126 for `Is a directory', so:

```
trap '
if [[ $? -eq 127 || $? -eq 126 ]]
then    _d=$( history 1 | awk "{ print \$2 }" )
        [[ -d "$_d" ]] && cd "$_d"
        unset _d
fi
' ERR
```

but, there's no need for any of this. Close reading the man-page tells us:

```
shopt -s autocd
```

already exists (knew I had seen that somewhere!).
