Yeah - this happened around 1964 if wikipedia is any guide.

Agreed - so let's not solve it permanently.

As already mentioned in this thread, a capability similar to what svn or
cvs offers would be sufficient. While a DVCS does offer unique
challenges, it seems to me that doing something at commit time without
requiring magic hooks be configured would go a long way to addressing
the problem. Magic hooks on the official repo would then be considered
the final fallback defense, but should rarely be invoked.

I'm not sure what point you are trying to make, but I believe it *is*
possible for a solution to be found here which will keep Windows users
happy. I'm guessing you haven't had much practical experience with this
problem, so probably don't see this is clearly as Windows users do.
