Lua do keyword is not matched with end

[andreyorst]

With the given Lua code:

function f() do
  local res = nil
  do
    -- side-effects
    res = 1 + 2
  end
end

Smartparens matches end of the function incorrectly:

This is extremely similar to #707 and can be fixed similarly, but raises the question if Smartparens should have a way to declare some heuristics for possible ambiguity in matches?
