If you dislike that, you could make the stretch one column shorter, like this: (let* ((align (list 'space :align-to `(+ (,(- (window-body-width nil t) (default-font-width))) ,(window-hscroll)))) (Btw, I think adding window-hscroll is incorrect here, as its value is in columns, while window-body-width returns the width in pixels.) > > I cannot do anything about these issues besides explaining how they > > harm Emacs maintenance, and asking people to look for alternative > > solutions. > > Well you *could* refuse to fix bugs like this, i.e. declare that > creating overlays with newlines invokes undefined behaviour. I could, but I consider that a "doomsday weapon", hopefully never to be used in Emacs development, certainly not by me. I don't think it was ever done.
