TYPE=.4 test fails on Allegro Beta 11: Allegro result seems consistent with spec
This test expects a return of `(nil nil)`, but on Allegro returns `(nil t)`. This is because on Allegro:
```
(subtypep 'string '(satisfies emptyp))
NIL
T
```
I don't think that it's wrong to return `(nil t)` from this `type=`, is it? I propose to modify the test to ignore the second value if you agree. This is in my fix MR !27
By the way, `type=.3` *also* fails on Allegro, but this one is a bug in Allegro, which I have reported to Franz.
