Pre-merge hook?

I think that would be very useful to have a pre-merge hook for master. So we can ensure that everything that goes to master passed the tests, but rely on the developer how they handle they own branches. Thoughts?

probably useful, and should not be difficult, there is already post-merge hook code. But I do not see pre-merge hook in the list of available Git hooks https://git-scm.com/docs/githooks
