If a key-value pair follows an empty list, i.e.:
```yaml
a:
-
b: c
```
yamllint will complain:
```
warning wrong indentation: expected 2 but found 0 (indentation)
```
This is because it is expecting the second key to be a continuation of
the block entry above:
```yaml
a:
-
b: c
```
However, both are perfectly valid, though structurally different.
