I got curious and took a look, it seems like this is related to
`sortDataDir` and the way it handles files that have a different "prefix" than
what is passed in.
```
* @param prefix files not matching this prefix are assumed to have a
* version = -1)
```
Not sure what the best way to handle this would be. I think throwing in a
check while iterating getLogFiles may be the simplest way to go. Maybe you
could think of something cleaner.
