Subject: vim-patch:8.2.0924: cannot save and restore a register properly

Problem:    Cannot save and restore a register properly.
Solution:   Add getreginfo() and make setreg() accept a dictionary. (Andy
            Massimino, closes vim/vim#3370)
https://github.com/vim/vim/commit/bb861e293e0170455184079fa537278754b07911
