bug#17623: 24.4.50; incorrect example for `apply-partially' in (elisp) `Calling Functions'

[Drew Adams]

The text states incorrectly that the example defines an equivalent of
built-in function `1+', but it does not.  The function defined in the
example is equivalent to this one, which is not equivalent to `1+':

(defun 1+-sum (&rest args)
 "Return one more than the sum of the args."
 (1+ (apply #'+ args)))

This function accepts any number of args, including zero.
`1+' requires a single arg.

As it stands, this example is liable to confuse more than help.
