I'm not sure about the significance of the other fields that differ, but 
by doing a bisect on the diffs, I discovered that the difference that 
causes the scrolling bug with neovim windows is caused by the `smglp` 
and `smgrp`.

So I suspect it should include `smglp@, smgrp@`?

It also looks like the upstream wezterm.terminfo uses several "user 
defined" capabilities. I'm not sure what ncurses policy is on using 
those, or what, if anything, consumes those.
