When the craft guide is showing a craft, the output slot is now a button, which causes the craft guide to show ways in which that output can be used. This mirrors the way input slots are buttons that show recipes for the selected ingredient. Usages of an item can be iterated through in the same way as recipes for the item. This incidentally offers some ability to retrace one's steps through a crafting chain, without storing actual history.

-- This pair of encoding functions is used where variable text must go in
|
|
-- button names, where the text might contain formspec metacharacters.
|
|
-- We can escape button names for the formspec, to avoid screwing up
|
|
-- form structure overall, but they then don't get de-escaped, and so
|
|
-- the input we get back from the button contains the formspec escaping.
|
|
-- This is a game engine bug, and in the anticipation that it might be
|
|
-- fixed some day we don't want to rely on it. So for safety we apply
|
|
-- an encoding that avoids all formspec metacharacters.
