Use git-config to Break your Config File

Gitsters,

I was fooling around and realized that I could assign an empty string as the name of a config section, like so:

    $ git config --rename-section my ''

This leaves the config file looking like this:

    []
        foo = goodbye

Which does not appear to be valid:

    $ git config --get '.foo'          
    fatal: bad config file line 13 in .git/config

So maybe git-config should disallow setting a section to an empty string?

Best,

David
