Thanks for figuring this out! I've been using my local (terrible)
workarounds for years to make this work.

I can't really advise on the best way forward here, but if you do decide
to go with the .patch route, you should probably also add your .patch
file to `dist_patch_DATA' in gnu/local.mk.

IMHO, software shouldn't assume certain permissions are set, and instead
check or make-it-so. Perhaps you could upstream your patch instead of
embedding it into Guix?
Furthermore, the same issue as the one your fixed here is also present
in our `emacs-org' package. Do you think your approach would work there
as well? If so, it might make sense to fix both emacs and emacs-org.
Thanks!
