vim-patch:8.2.4359: crash when repeatedly using :retab
Problem: crash when repeatedly using :retab.
Solution: Bail out when the line is getting too long.
https://github.com/vim/vim/commit/6e28703a8e41f775f64e442c5d11ce1ff599aa3f
Cherry-pick e_resulting_text_too_long from v8.2.3492; put it in globals.h as
it will eventually be used in other files.
Add a modeline to test_retab.vim
