How the Lua beautifier works

Lua blocks are delimited by keywords rather than braces, so the beautifier re-indents by counting function, do, then and repeat against end and until, treating else/elseif as a step back. Strings, comments and multi-line [[…]] strings are left untouched. if x then print(x) end written on three flush-left lines comes back with print(x) indented four spaces.
