Yes, and this is still the case for _reading_. But the current case is
about deciding which file to use when _writing_. Git was already dying
when writing with an unset $HOME. There is no behavior change in this

With Junio's suggestion, we would have a behavior change in that we
would write to the XDG file if we can find it (using XDG_CONFIG_HOME,
obviously, since $HOME is unset in this case).
