        <pre>clang-format 3.8.0 (OS X) produces this formatting:
{{{
struct X {
  template <typename T1 = T, typename S = typename T1::scalar_t, typename S1>
  void storeu(const conserved_t<S1 * restrict> &vars, ptrdiff_t idx) const {
    map([&](T var,
            S1 *restrict varptr) { return var.storeu(varptr[idx]), var; },
        *this, vars);
  }
  template <typename T1 = T, typename S = typename T1::scalar_t, typename S1>
  void storeu_partial(const conserved_t<S1 * restrict> &vars, ptrdiff_t idx,
                      ptrdiff_t i, ptrdiff_t imin, ptrdiff_t imax) const {
    map(
        [&](T var, S1 *restrict varptr) {
          return var.storeu_partial(varptr[idx], i, imin, imax), var;
        },
        *this, vars);
  }
};
}}}

The first call to {{{map}}} is formatted fine. The second call has an
unnecessary line break between the opening parenthesis and the beginning of the
lambda expression.</pre>
