Yeah... I found your change on the wiki after I asked here (I'm on a phone, so... a bit clunky...)
That wiki is getting a bit messy, but your change probably would better fit on the next page. This is an example of "Item Amend" (m} y) and you put your change on the page for amend (x m} y). The next page is supposedly for the (u} y) form, but has also managed to collect a (x m} y) example... Anyways... it's getting to be messy...
