We have thus far reformatted OBJ_TREEs with a new dictionary based

All trees are then converted to use a 22 byte record format:

  - 2 byte network byte order index into the string pool
  - 20 byte SHA-1

Umm. Am I missing something, or is this totally braindamaged?

Are you really expecting there to never be more than 64k basenames? Trust 
me, that's a totally broken assumption. Anything that tracks generated 
stuff will _easily_ have several tens of thousands of random filenames 
even in a single tree, much less over the whole history of the repository.
