Fix possible arbitrary code execution via Vim's Python omni-completion. The runtime scripts would reconstruct function and class definitions from the buffer using exec(), and docstrings were inserted verbatim between triple quotes with no escaping. A hostile buffer could break out of the triple-quoted literal and execute attacker-controlled Python during omni-completion. Use repr() on doc strings instead of triple-quote wrapping to prevent code injection via crafted docstrings in python3complete.vim.
