No! The three func_*_arg* pages only contain one example about the
usage of the func_*_arg* function.
The examples I am asking for are about the usage of variable-argument
functions in general, and they (or similar) are not included anywhere in
the docs.
Why don't you just include them? More examples make the docs better,
since anybody who is not interested can easily skip them. But for those
who don't know how things work, examples are a GREAT way of showing.

Examples are on the func_*_arg* pages which are linked from this
section.

Description:
------------
Please include examples on how to define (and call) functions with a
variable number of arguments:
Example 17.11. Define a function with variable number of arguments:
function test() {
echo func_get_arg(0);
}
test('hello'); // prints 'hello'
Example 17.12. Other method to define a function with optional second
argument
function test($foo, $bar=null) {
echo $bar;
}
test('one','two'); // prints 'two'
test('one'); // prints nothing
Example 17.13. Wrong way to define a function with optional second
argument
function test($foo, $bar) {
...
}
test('one'); // gives warning, that argument 2 is missing for test()
Why am I asking for this?
Because the current explanation "No special syntax is required" is not
very descriptive. So my first guess was the wrong way shown in Example
17.13
