But you can add _yet another_ index to it, which can be generated on the 
fly, so that Git only has to generate the information once, and then reuse 
it later.  As a benefit of this method, the underlying well-tested 
structure needs no change at all.

BTW could you please, please, please cut the quoted message that you are 
_not_ responding to?  It really _wastes_ my time.
