Right, I'd expect that to work, but...

There's another difference when asking to read from a specific file:
includes are not turned on by default. Try

  git -C ... config --global --includes user.email

This is covered briefly in git-config(1):

  --[no-]includes
    Respect include.* directives in config files when looking up values.
    Defaults to off when a specific file is given (e.g., using --file,
    --global, etc) and on when searching all config files.

This can be confusing, but was necessary to keep compatibility with
scripted manipulations of those files when includes were introduced.
