Scratch that. I can't reproduce #16377 in Emacs 25.2.1, undo-tree git
head, except by calling undo-tree-undo/redo commands via M-x in buffers
where undo-tree-mode is disabled.
Calling undo-tree commands with undo-tree-mode disabled is entirely
expected to mess up buffer-undo-list. I've added checks in git to all the
undo-tree interactive commands to throw a user-error if they're called
when undo-tree is not enabled, to guard against this.
But that has nothing to do with the original bug, which appears to
already be fixed in git.
