I'm pretty sure it will in fact be easier to use save-cwd from Gnulib,
and I'm already working on patches in that direction.  (The only real
obstacle is that GRUB's use of Gnulib is currently a bit of a mess, so
I'm working on cleaning that up first.)  Of course you're free to submit
a patch upstream implementing your preferred approach, but this is mine.
