Subject: vim-patch:8.2.1413: previous tab page not usable from an Ex command

Problem:    Previous tab page not usable from an Ex command.
Solution:   Add the "#" argument for :tabnext et al. (Yegappan Lakshmanan,
            closes vim/vim#6677)
https://github.com/vim/vim/commit/94f4ffa7704921a3634e56b878e6dc362bc3d508

Do not rename old_curtab to prev_tp in win_new_tabpage, this can be confused
with the previous tabpage (`:tabprevious`).

Cherry-pick ex_errmsg from v8.2.1280.
