The latter, I'd think, as you noticed in 2. the former does not make
much sense.

Yes, I think the intent of the problem specification is "if it is
found in the XDG_CONFIG_HOME use $XDG_CONFIG_HOME/.config/git/* a
the location to place it; by the way if the user does not have
anything to explicitly say she wants to use a specific location for
XDG_CONFIG_HOME, it defaults to "~/.config, hence the Git specific
location becomes ~/.config/git/*".

Let me be vague and oblique on purpose ;-)

We used to have only ~/.gitconfig as the per-user location, and at
some point in the history we added XDG_CONFIG_HOME support.  Study
how that was done (hint: "git log" and "git blame" may be useful
tools for this purpose), and imitate it.
