patch 8.2.1967: the session file does not restore the alternate file
Commit: https://github.com/vim/vim/commit/59d8e56e048eb5d384649284fb35363931fc3697

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 #7269,
closes #6714)
