Since we are still making relatively "heavy" changes (groff and
ghostscript), I'll apply these patches without a graft on core-updates.
Then we should freeze it, for real :)

I looked into applying the upstream patch releases. It's not trivial,
because some of them are "just patches" and some of them are shell
scripts. So, we'll need to do write some special code to build ncurses.
I'd rather continue with core-updates and do this later.

Also, I'd like for us to download these patch releases when needed
instead of including them with Guix.

It will mean that ncurses will almost always be grafted...
