Motivation for this change
Un-break ncurses6 on clang (it's been broken a long time).
Recent hydra log demonstrating this on Darwin: https://hydra.nixos.org/build/66447097/nixlog/3
Follow-up might want to enable ncurses6 on Darwin instead of using 5, not sure if there are other reasons for using 5 on Darwin but 6 on Linux. (cc @LnL7 @copumpkin).
First commit simplifies and is what I think is "best"; second shows what it would look like to un-break ncurses6 on clang but avoids triggering mass-rebuild... at the cost of being significantly uglier :).
I'm good with either being merged, wasn't sure how folks would feel.
