This reroll should fix all comments I have received in v3. I reordered the shallow checks a bit so in common case it should be as cheap as a normal fetch or push. See 08/28 and 20/28 for the big picture. I'm not entirely happy with the hook issue in 20/28, but it looks good enough for me. There are a few XXXes for further improvement, but I'll keep them until this lands.
To recap, this series allows you to clone from a shallow repo, push to or fetch from any shallow repo. Normally it will reject new refs that introduce new shallow boundaries to your repository, so if you're in a full clone, it will always stay a full clone. Use "fetch --update-shallow" or set receive.shallowupdate to accept those refs.
