Possible patch
When parsing the following stream:
```yaml
- 1
- 2
3
- 4
- 5
```
Using the ``yaml::Input`` class, an error is printed but the ``error()`` method
does not correctly report the issue.
I've been digging through the code and it appears that (some) scanner errors
are not reported at the Input level.
The attached patch demonstrates a possible fix + unittest, I wonder if an
auxiliary method would make it more readable?</pre>
