This was closed before I had a chance to comment on the wording but a few things: First, this text doesn't mention the .WAIT prerequisites that were added as optional features; do we need to add text for how these are included (or not) in $^? Or, are they just included like any other prerequisite? Or did .WAIT not get included? I can't remember. This was the subject of https://austingroupbugs.net/view.php?id=1520 which itself doesn't mention the removal of duplicate entries, as the above text does. Second, the wording of the $^ implies that when duplicates are seen the it's always the first instance which is preserved and subsequent instances are omitted, which means order is preserved. Is that requirement intentional? I think I'm confused :).
