The path name field needs to be moved back into the blobs to support

of recovering the path name for these blobs other than a brute force
search following every path looking for the right SHA.
Ah, there we go. A use-case at last :)
But not a brilliant one. You sign off on commits not blobs. So you go
from the sign-off to paths, then to blobs. There is no need to go from
blob to path unless you deliberately introduce such a need.
Use blame for an example. Blame has to crawl every commit to see if it
touched the file. It keeps doing this until it figures out the last
author for every line in the file. Worse case blame has to crawl every
commit in the data store.
Estimated daily uses of git-blame, world-wide: few
Estimated daily uses of git-{merge,diff}, worldwide: lots
Code and benchmarks, or I'm not buying it.
