Martin is trying very hard to come up with a method to overcome the fact that Emacs cannot display "rectangular" overlay strings. Breaking the string into several one-line strings and putting their overlays at the appropriate buffer positions would solve this problem. > One-line-per-overlay approach will always work worse in display-heavy > buffers, for instance. Like the 'M-x report-emacs-bug' one. Why would it work worse in that case?
