Correctly format wrapped function call parameters in templated functions.

Before:
template <typename T>
void aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(
        int aaaaaaaaaaaaaaaaa);

After:
template <typename T>
void aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(
    int aaaaaaaaaaaaaaaaa);
