Looks like this fails CI on the Windows VS build. I get:

  ++ env GIT_CONFIG_GLOBAL=does-not-exist GIT_CONFIG_SYSTEM=/dev/null git config --global --list
  fatal: unable to access 'nul': Invalid argument

from t1300.181. I thought we had some magic to make /dev/null work there
(or maybe this _is_ the magic kicking in, since it is looking for the
Windows-ish nul, but it is not working for some reason).
