Fetch-hooks

Hello,

tl;dr: Is there currently a way to have fetch hooks, and if not do you think it could be a nice feature?

I was in the process of implementing hooks for git that ensure the repository is always cleanly signed by someone allowed to by the repository itself. I think I've completed the signature-checking part [1] and the push hook [2] (even though it isn't really configurable at the moment).

However, I was starting to think about handling the fetch step, and couldn't find any fetch hook. Is there one?

If not, would you think it is would be a good idea to add one, that would eg. be passed the commit-before, commit-after and could block the changing of the reference if it failed?

The only other solution I could think of is using a separate script for fetching, but that would be fragile, as the user could always not think about it well and run a git fetch, breaking the objective that after the first clone all commits were correctly signature-checked.

Thanks for reading me! Leo
