patch 9.0.1686: undotree() only works for the current buffer Commit: https://github.com/vim/vim/commit/5fee11114975b7405b7ccd3ee8758e54bf559760 Author: Devin J. Pohly <djpohly@gmail.com> Date: Sun Apr 23 20:26:59 2023 -0500 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. closes: #4001 closes: #12292 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: zeertzjq <zeertzjq@outlook.com> Co-authored-by: Devin J.
