[PATCH v3 0/4] Delete ignore_env member in struct repository

[Nguyễn Thái Ngọc Duy]

v3 fixes comment style. Also since Brandon raised a question about
shared_root, it's obviously not a good name, so I renamed it to
commondir.

I still keep the delete patch 2/4, but I move the repo_setup_env()
deletion back to 1/4 so all env logic is in one patch (the
introduction of new helper functions in 1/4 and deletion in 2/4 are
still diff noise if 2/4 is completely merged back).
