I know it does in many cases, but as you've found out it doesn't
always work.

I saw that yes.  And I think that given the docstring, the patch should
not let-bind default-directory but just setq it (or do nothing at all).

AFAIK it's been that way for ever, so backward compatibility is not
really relevant.
