Title: _parseIndented() crashes when there is no trailing newline

Given test output like:

```
not ok 1 Error: beep boop
---
stack:
- rawr
- dinosaurs
...
```

except without a trailing newline crashes _paseIndented() because this._indent has undefined elements. This patch and test add a check for undefined elements to fix this crashing behavior.
