Review comment:
Ohh I think the comment is a bit misleading. So the condition below only
skips if there is a signature but no docstrings, right? So for example it still
validates the following:
```python
In [9]: print(ds.Dataset.get_fragments.__doc__)
Dataset.get_fragments(self, Expression filter=None)
Returns an iterator over the fragments in this dataset.
Parameters
----------
filter : Expression, default None
Return fragments matching the optional filter, either using the
partition_expression or internal information like Parquet's
statistics.
Returns
-------
fragments : iterator of Fragment
```
