Perhaps it would be better for overlays to evaporate by default. I tend to agree this would make things better in most cases, and only be wrong in a few. However, it is an incompatible change, and in some places it WILL break code.
It occur to me that we could make it easier to find those places. Suppose that by default the `evaporate' property is set to `display-warning'. Suppose that in this case, when the overlay becomes empty, it evaporates and displays a warning using `display-warning'. On seeing the warningm programmers would adapt their programs to set `evaporate' either to t or nil and thus prevent the warning. In Emacs 23, we could change the default to t. _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-devel
