The original is not easy to read, but this is not that much of an
improvement.  I think what the original wants to say is

    - write to global `~/.gitconfig`

    - but write to the XDG place instead, if XDG one exists and
      ~/.gitconfig does not exist

How about touching a bit more, e.g.

	For writing, rather than writing the per-repository config
	file .git/config, write to the global config file, which is
	$XDG_CONFIG_HOME/git/config (if it exists), or
	$HOME/.gitconfig (otherwise).

to streamline the description?

Correct, even though I would say s/thus ignoring/in order to ignore/
instead ;-)

Thanks.
