Can probably be simplified to (propagated-inputs (list r-askpass)).

Likewise.

Likewise.

Either https://jeroen.cran.dev/gpg/ or <https://github.com/jeroen/gpg>,
the combination gives a 404 Not Found.

Maybe make sure that it only invokes the "gnupg" by absolute file name
such that this isn't the case.

While theoretically Guix supports cross-compilation to Windows, I don't
see GPG4Win in the package inputs and I'd expect cross-compiling r-gpg
to Windows to fail, so I would remove this paragraph since currently
it's a bit misleading.
