Docs: clarify treatment of variadic functions with zero variadic arguments.
Explain that you have to use "VARIADIC ARRAY[]" to pass an empty array
to a variadic parameter position. This was already implicit in the text
but it seems better to spell it out.
Per a suggestion from David Johnston, though I didn't use his proposed
wording. Back-patch to all supported branches.
