Negative `timedelta` string representation is ambiguous.

```
>>> from datetime import datetime, timedelta
>>> d2 = datetime.now()
>>> d1 = d2 - timedelta(days=42, seconds=5)
>>> str(d2 - d1)
'42 days, 0:00:05'
>>> str(d1 - d2)
'-43 days, 23:59:55'
```

I would expect `str(d1 - d2)` to be one of the following:
* '-42 days, 0:00:05'
* '-(42 days, 0:00:05)'
* '- 42 days, 0:00:05'

I would be happy to submit a PR if there would be an agreement on the format.
