Oops sorry, my bad, I should have included an example in the commit 
message. So with git 2.8.0, if you provide a name and set useConfigOnly 
to true in your ~/.gitconfig file, then if try to commit something in a 
new git repo, it will fail with the following message:

    *** Please tell me who you are.
    
    Run
    
      git config --global user.email "you@example.com"
      git config --global user.name "Your Name"
    
    to set your account's default identity.
    Omit --global to set the identity only in this repository.
    
    fatal: unable to auto-detect email address (got 'XXX@YYY.(none)')

(provided of course that auto-detection of email fails). This wrong, 
because auto-detection is disabled anyway.
