That's a great point.  I didn't really consider this, and currently this particular case won't align the case statements if they have an empty case block, however if you had some tokens (e.g. `// fallthrough`) it would.  It's not immediately clear to me what the expectation would be.  I guess to align as if there was an invisible trailing token, but it's a bit awkward if the cases missing a body are the 'long' cases that push out the alignment.  Also, I don't think it's possible to use `AlignTokens` and get this behavior, as there is no token on those lines to align, so it's not straightforward to handle.  I guess I'll be curious to see if there is feedback or cases where this behavior is desired, and if so, I can look into adding that functionality later.  Since right now it would involve a completely custom AlignTokens clone, my preference would be to just leave this as not supported.
