bug#14278: 24.3.50; doc of `defstruct'

[Drew Adams]

6. The manual says "(The SLOTS may begin with a string which documents the
structure type.)".  The doc string says nothing about this.

7. Does this mean that SLOTS can begin with a string or each element of SLOTS
(each slot) can begin with a string?  (Another problem with trying to make
"SLOTS" do double-duty in the doc. 

8. And in either case, how does such a string "document the structure type"?
(Is it instead perhaps a part of NAME and not SLOTS?)

I see nothing in the Common Lisp defstruct that resembles such a "string which
documents the structure type".  Searching the relevant sections of CLTL2E for
"doc" and "string" turns up nothing in this regard.

9. The doc should say, if it is true (as in Common Lisp), that no part of the
defstruct options is evaluated (unlike the case for SLOTS).
