You know, I got caught by something very similar to this myself. I  
then proposed a feature on this list which would solve this problem,  
but got so badly flamed over the idea of noticing empty directories,  
logging a warning, and waiting a day before deleting everything, I  
sort of lost interest in the idea.

I want to make this easier in v0.11, basically by being able to roll  
back to any particular time. I have designed it, just need to write it.

No, it won't be that clever.

Read list archives. :-)
