Just as a data point, there is already one 7-hex-digit collision in our
repository:
Branch: master Release: REL6_1 [aaeef4dae] 1997-04-09 08:29:35 +0000
Branch: master Release: REL6_1 [aaeef4d17] 1996-11-10 03:06:38 +0000
I think it's quite foolish to depend on abbreviated hashes to be unique
forever.
