bug#17507: Documentation for `add-text-property' and relatives

In lisps you can mutate properties of an object, but you cannot change
the pointer itself.  I think that another way to clarify it would be
to say that "foo" is actually shorthand for #("foo") but the #() is
omitted for brevity.  But at this point this is subjective enough to
be ignorable...
