Use the ERR trap?

```
command_not_found_handle() {
	return 127
}

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

Ugly, but, works--after a fashion:

- Only for DIRs in the CWD.
- no `/' allowed in DIR.
- if CMD with the same name as DIR is found in $PATH, that will be executed.

Ayup, dunno what's up with that.
