Problem: vim.json.encode escapes every slash in string values (for example in file paths), and is not optional. Use-case is for preventing HTML injections (eg. injecting `</script>` closing tag); in the context of Nvim this is rarely useful. Solution: - Add a `escape_slash` flag to `vim.json.encode`. - Defaults to `false`. (This is a "breaking" change, but more like a bug fix.)
