What is the right style for multiple params in a function? There are 4 different styles in this diff:

``` cpp
HashIntoType * CountingHash::fasta_count_kmers_by_position(
    const std::string &inputfile,
    const unsigned int max_read_len,
    BoundedCounterType limit_by_count,
    CallbackFn callback,
    void * callback_data)

void CountingHashFile::save(const std::string &outfilename,
                            const CountingHash &ht)

CountingHashFileReader::CountingHashFileReader(const std::string &infilename,
        CountingHash &ht)

CountingHashGzFileReader::CountingHashGzFileReader(const std::string
        &infilename, CountingHash &ht)

```
