Currently a score that looks like |||||| will contain five bars. This should be 0 bars so that scores can look like this:

| q q q | q q q |
| q q q | q q q |

Note the barline at the end of the line and at the beginning of each line. This should be optional, making:

| q q q | q q q
| q q q | q q q |

also a valid score. But in my opinion, the first variant looks nicer and is more analogous to traditional notation.
