Tweak selection-undo interaction with WinDisplay hooks Each selection undo operation is surrounded by pair of begin_edition()/end_edition() calls. The original reason for adding these was that in one of my preliminary versions, a WinDisplay hook could break an undo chain, even if the hook did not affect selections at all. This has since been fixed. By surrounding the undo with begin_edition()/end_edition(), try to ensure that any selection modification that happens in a WinDisplay hook would not break the undo chain. Essentially this means that, after using <c-h> to undo a buffer change, this was meant to make sure that <c-k> could redo that buffer change. However, it turns out this actually doesn't work. The attached test case triggers an assertion. As described in the first paragraph, the only real-world motivation for this is gone, so let's simplify the behavior. The assertion fix means that we can test the next commit better. 2022-12-22 18:09:45 +01:00			`ui_out -ignore 4`
