Something much simpler would be to set core.abbrev at clone time,
depending on the size of the project just cloned. So, when cloning a
hello-world, we'd keep the 7 but when cloning a big project we'd get a
larger value.
This doesn't cover the case of someone growing his own project without
cloning, and isn't as clever as actually looking for colision, but it
would probably provide a sane default in 99% cases, and wouldn't be
worse than hardcoding 7 in the 1% remaining cases.
