vim-patch:8.2.2440: documentation based on patches is outdated (#39144)

Problem:    Documentation based on patches is outdated.
Solution:   Add changes to documentation in a patch.

https://github.com/vim/vim/commit/853886722c051ecaef6d818ce32a822e4f43dc2b

Trailing space was removed in later patches.
Also fix a few more misplaced error numbers from #8155.
