[elpa] externals/undo-tree 35a438bee8 3/9: Fix how undo-tree-viualizer-timestamps|diff are set buffer-local.

[Stefan Monnier]

branch: externals/undo-tree
commit 35a438bee8222247aa1e173456d0fb3fac30994d
Author: Toby S. Cubitt <toby-undo-tree@dr-qubit.org>
Commit: Toby S. Cubitt <toby-undo-tree@dr-qubit.org>

    Fix how undo-tree-viualizer-timestamps|diff are set buffer-local.
    
    Major-mode fundctions call `kill-all-local-variables' at start, so these 
need
    to be made buffer-local *after* setting the major-mode to
    undo-tree-visualizer-mode, not before. We now set them buffer-local in
    undo-tree-visualizer-mode, which seems the appropriate place.
    
    (Thanks to Martin Joerg for flagging this.)
