Auto-end code blocks

I am not sure if this is an Atom feature or a language grammar feature (or both?) but Atom seems to enjoy adding closing syntax such as brackets, braces, and quotations when you type the opening equivalent. It would be pretty nice if this grammar could auto close code blocks that use "end" such as:

``` lua
function name()
end

name = function()
end

for i=1, 10 do
end

for i, v in ipairs(t) do
end

for k, v in pairs(t) do
end

while true do
end

do
end

if true then
end
```
