Update comment about set_join_pathlist_hook(). The comment introduced by commit e7cb7ee14 was a bit too terse, which could lead to extensions doing different things within the hook function than we intend to allow. Extend the comment to explain what they can do within the hook function.
Back-patch to all supported branches. In passing, I rephrased a nearby comment that I recently added to the back branches. Reviewed by David Rowley and Andrei Lepikhov.
