Demonstration of remove_item bug
--]]

minetest.register_node("testmod:test", {
    description = "test",
    groups = { snappy = 3 },
    on_use=function(itemstack, user, pointed_thing)
        inv=minetest.get_inventory({type="player",name=user:get_player_name()})
        inv:remove_item("main",ItemStack("testmod:test"))
    end,
})

To see the bug save this as the init.lua of a mod, then in game do /giveme testmod:test 20
It should be that upon left click a single "test" item is removed from player inv.
But that does not happen unless there is a stack of the "test" item at some point AFTER the player's currently selected inventory slot.
