In the encoded file, or if the attributes are changed but the file  
contents not, in the directory.

You can find the exact size by going through the block index,  
decrypting the encrypted section of each entry, and summing the  
uncompressed size. So it would duplicate data for little gain.

I'm happy to consider it for the redesign, but I feel that adding it  
now is going to be painful due to having to test stores with mixed  
old and new formats.
