patch 8.2.4919: can add invalid bytes with :spellgood Commit: https://github.com/vim/vim/commit/7c824682d2028432ee082703ef0ab399867a089b Author: Bram Moolenaar <Bram@vim.org> Date: Sun May 8 22:32:58 2022 +0100 patch 8.2.4919: can add invalid bytes with :spellgood Problem: Can add invalid bytes with :spellgood. Solution: Check for a valid word string.

" A series of tests that can run in one Vim invocation.
" This makes testing go faster, since Vim doesn't need to restart.

" These tests use latin1 'encoding'.  Setting 'encoding' is in the individual
" files, so that they can be run by themselves.
