I had these set up in the first place mostly because GNU ls supports
--color=auto and the BSD ls provided with MacOS didn't, causing problems
if I aliased ls to ls --color=auto.
And I don't really need that any more, especially since I prefer to use
lsd-rs/lsd in place of the coreutils ls nowadays. Additionally, the BSD
ls that comes with MacOS now *does* support that flag, so in a pinch it
can do what I need.
Defaulting to the natively installed coreutils should help my usage of
these tools more portable too, rather than always relying on GNU-isms.
Given my huge reliance on Zsh-specific features that's not something I'm
doing super well anyway, but still.
