Diff pane too wide, buttons move off screen

In 'File Status' view, the diff pane on the right can get rather wide, if at least one wide line is displayed. This moves the 'Stage hunk' etc. buttons off screen. The changes relevant for decision whether to stage/unstange/discard a hunk are usually on the left edge, the buttons on the right one. The consequence is that I have to constantly scroll left and right because some line further down has of yet unreviewed changes. I hope I'm not missing an option for this... it's very annoying.
