Looks like another bug that I'll investigate next.

I think undelete is the easiest approach. The support for delete and 
undelete with the -i option was not fully implemented, but wasn't hard to 
add, so I've just done it in the 0.11 branch. Please could you check that 
out and try to undelete the directory that you want using that option?

Sorry for the difficulty!

Cheers, Chris.
