patch 9.0.1686: undotree() only works for the current buffer
Commit: https://github.com/vim/vim/commit/5fee11114975b7405b7ccd3ee8758e54bf559760

patch 9.0.1686: undotree() only works for the current buffer
Problem: undotree() only works for the current buffer
Solution: Add an optional "buffer number" parameter to undotree(). If
omitted, use the current buffer for backwards compatibility.
