> HRegion#get(Get) adds/validates column families. The resulting RegionScanner
> goes through the same validation dance a second time. That second
> implementation is slightly less efficient, always checking the families, even
> if there were no user-provided families and the prepareScanner() call already
> did this. The current logic in HRegion#get() is smarter actually. Let's do
> the work only once.
