At least on Windows, chdir() does not update PWD. Unfortunately, stat()
does not fill any ino or dev fields anymore, so get_pwd_cwd() is not
able to tell.
But there is a telltale: both ino and dev are 0 when they are not filled
correctly, so let's be extra cautious.
This happens to fix a bug in "get-receive-pack working_directory/" when
the GIT_DIR would not be set correctly due to absolute_path(".")
returning the wrong value.

This patch fixes that.
Hannes, I have no idea whether you meant 10c4c881 to fix anything
on Windows.
