vim-patch:8.2.{1536,1540}: charclass() (#19748)
vim-patch:8.2.1536: cannot get the class of a character; emoji widths are wrong
Problem: Cannot get the class of a character; emoji widths are wrong in
some environments.
Solution: Add charclass(). Update some emoji widths. Add script to check
emoji widths.
https://github.com/vim/vim/commit/4e4473c927167fd24e5c8df90e0e8035080cf2da
Use latest charclass() docs from Vim.
Rewrite DoIt() in emoji_list.vim in Lua.
Omit emoji table updates:
- emoji_width update looks wrong as these added ranges are only double-width when followed by 0xFE0F.
- Other updates are too old.
vim-patch:8.2.1540: the user cannot try out emoji character widths
Problem: The user cannot try out emoji character widths.
Solution: Move the emoji script to the runtime/tools directory.
