The text you are quoting is not about what is in the config file, but
rather the config name given on the command line (which we would be
trying to look up). And we do correctly complain about that:

  $ git config foo
  error: key does not contain a section: foo

But:

Yes, everything is supposed to be in a section.  Historically we have
not complained, but instead just treated it as a single-level variable.
For internal git use this never mattered, as git only looked at
variables with section names. For "git config foo", it also does not
matter, since we will notice the lack of section before even doing a
lookup.

For "git config --list", as you noticed, we include it in the output. I
suspect we should simply omit it as cruft. But we could also issue a
warning, and/or die.
