bug#14278: 24.3.50; doc of `defstruct'

[Drew Adams]

Both the doc string and (cl) `Structures' are a bit sloppy in their
descriptions.  SLOTS is the name of one parameter.  It is incorrect to
speak of SLOT unless that has been defined as one of the elements of
list SLOTS.  And it needs in fact to be said that SLOTS is a list.
 
The doc string says "Each SLOT may instead..." - instead of what?  It
forgets to say that a slot can be a symbol.
