Detailed Description

Temporary action for MCR undos.

This is intended to go away when real MCR support is added to EditPage and the standard undo-with-edit behavior can be implemented there instead.

If this were going to be kept, we'd probably want to figure out a good way to reuse the same code for generating the headers, summary box, and buttons on EditPage and here, and to better share the diffing and preview logic between the two. But doing that now would require much of the rewriting of EditPage that we're trying to put off by doing this instead.

Since: 1.32
