DOCUMENTATION does not work for generic functions

[Mark Evenson]

DOCUMENTATION does not seem to be able to retrieve the docstring for generic functions:

(defgeneric foo nil (:documentation "Ipso facto"))
#<STANDARD-GENERIC-FUNCTION FOO {6901DFA5}>
CL-USER> (documentation 'foo 'function)
NIL

If one inspects the generic function in SLIME, one sees that the documentation slot does have a value, so this is a problem in DOCUMENTATION.

[Mark Evenson]

Added failing test in r13609.

But passing in the actual function object to DOCUMENTATION works:

LISP> (documentation #'foo t)
"foo"

Need to check the specification a little closer.

[Mark Evenson]

More of a problem in passing the information around the CLOS code.

By following the argument passing around clos.lisp, one could probably fix this reliably.

(In [13750]) Fix #172: DOCUMENTATION now works for generic functions.

LispObject.java didn't know that things other than Function could be
in a symbol's function slot.
