Sometimes someone accidentally makes a change to an item on a branch or makes a change that they change their mind about.

In either case, it is ideal to get rid of the change from the review screen. But it can be hard because the change was very minor but hard to detect what was changed and therefore revert. Or these changes can be big and hard to reproduce exactly what was changed.

So a "Revert Changes" button on the reveiw screen would be very useful to simply revert the changes without any detective work.

An example is attached where there is an additional newline but the review screen does not highlight it.
