SC2329 - false positive when passing function to another function

[mkp76]

For bugs with existing features

• Rule Id: SC2329
• My shellcheck version: v0.11.0
• The rule's wiki page does not already cover this (e.g. https://shellcheck.net/wiki/SC2086)
• I tried on https://www.shellcheck.net/ and verified that this is still a problem on the latest commit

Here's a snippet or screenshot that shows the problem:

#!/bin/bash

function foo1() {
	local fn=${1}
	echo "foo1"
	${fn}
}

function foo2() {
	echo "foo2"
	return 0
}

foo1 foo2

exit  0

Here's what shellcheck currently says:

Line 9:
function foo2() {
^-- SC2329 (info): This function is never invoked. Check usage (or ignored if invoked indirectly).

Here's what I wanted or expected to see:

No issue
