You should never edit DefaultSettings.php unless you're hacking up the
main software itself; avoiding that is why we have extension hooks in
the first place. Put customizations in LocalSettings.php.

This function won't actually do anything, obviously, as it consists only
of a comment and a true return. It won't even produce any evidence that
it's being run unless you're stepping line by line in a debugger; how
are you checking whether or not it's running successfully? What's the
problem that you're posting about?

In your own file, which you can include from LocalSettings.php. The
purpose of hooks is to allow adding in some functions *without* changing
the core code.

I tried putting this into my test REL1_4 installation's
LocalSettings.php:

$wgHooks['ArticleSave'][] = 'myFunction';   // new
function myFunction() {
	die("Testing!");
}

When I try to save, the script dies and prints "Testing!" as expected,
showing clearly that the hook is run.
