When I read that it's not clear if the local level discards the global level completely or it's aggregated. If we specify that it's only the variables that take precedence it might be clearer:
Git's configuration is composed of variables that are stored in multiple locations: 'system' (all users), 'global' (for the user), and 'repository' -- in decreasing order of precedence.

I think we should only mention (once) the system wide configuration, but not cover it. That's for system administrators, not users.

I have separate patches for 'git config --edit', but Junio suggested to hold them back because --edit is a relatively new option.

I disagree. Most useful configurations (color.ui, user.email) should be global. The complete newbie might think: cool, now I have my git properly configured (with 'git config -e'), and then when cloning a new repo (s)he would think: ok, git just forgot what I told him. When that happens (s)he would have to re-learn and re-configure git.
When users think about configuration, it's usually a 'global' configuration, so that's what we should teach from the beginning and make sure they understand the difference between 'global' and 'repository' configurations.

Looks better, except s/configuration options/configuration variables/
