Subject: vim-patch:8.2.1967: the session file does not restore the alternate
 file

Problem:    The session file does not restore the alternate file.
Solution:   Add ":balt".  Works like ":badd" and also sets the buffer as the
            alternate file.  Use it in the session file. (closes vim/vim#7269,
            closes vim/vim#6714)
https://github.com/vim/vim/commit/59d8e56e048eb5d384649284fb35363931fc3697

Include minimal test_buffer.vim from patch 8.2.0243 for Test_balt().
Add entry for :balt to runtime/doc/index.txt from vim/vim#7819.
