I do. I'll be using them in preview-latex for the spliced image stuff, and everything preview-latex does is done by overlays: copy&paste does not transfer the images, so it should not transfer the line compression. I could perhaps get by by using text-properties on a newline tacked into the after-string of overlays. Of course this would mean exercising the display engine pretty heavily, pushing my luck. But better now than after a release. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum
