Wow. Well spotted.
When D is left unset, we end up executing
cd "" && ...
and it explains why nobody noticed the breakage for nearly a year
since c0192df6 (refspec: add support for negative refspecs,
2020-09-30) was written.
Unlike the apparent
copy-and-paste source, this is a more modern script that limits the
chdir inside subshells to avoid moving around in the main flow of
the test, and the fix proposed here looks the most sensible.
