Ah, I think I see the real problem is. Alias handling is done too early, and for commands like init-db that does _not_ even want to look at an existing repository it tries to use GIT_DIR.
So how about this patch instead on top of yours?
-- >8 -- git alias: try alias last.
This disables alias "foo" from being used for git-foo, and when we do use alias we check the built-in and then existing command names first and then alias as the fallback. This avoids the problem of common commands used in scripts getting clobbered by user specific aliases.
