incorrect func referencing

[ferib]

Original:

local function simplifyDPStep(points, first, last, sqTolerance, simplified)
    local maxSqDist = sqTolerance
    local index

    for i=first+1, last do
        local sqDist = getSqSegDist(points[i], points[first], points[last])

Output:

local function unknown3(var0, var1, var2, var3, var4)
        local var5 = var3
        local var6 = nil; 
        local var7 = var1 + 1
        local var8 = var2
        local var9 = 1
        for var10=var7, var8, var9 do
                local var11 = "unk1"
