patch 8.1.1280: remarks about functionality not in Vi clutters the help
Problem: Remarks about functionality not in Vi clutters the help.
Solution: Move all info about what is new in Vim or already existed in Vi to
vi_diff.txt. Remove {not in Vi} remarks. (closes #4268) Add
"noet" to the help files modeline. Also include many other help
file improvements.
