Care to explain why?

Since this code is mine I can tell you that no official GIT version ever 
produced such a pack.  The code to make use of that bit was quite 
involving and the end result wasn't great at all so I never published 
said code.  This is also why current GIT accepts both pack version 2 and 
3 without any distinction using the same code in patch-delta.c on the 
basis that no version 2 packs ever used that bit.
