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. -- Matthieu Moy http://www-verimag.imag.fr/~moy/
