Why is that a problem? Your original feature is still there (albeit under a slightly different name), and there's an _additional_ feature as well. How is that a problem? > I attach three possible solutions, in order of personal preference: I'm sorry, I'm unable to discuss solutions to a problem I don't understand. Once again: what is the problem that needs to be fixed here, and why? That Emacs behaves slightly differently from your original code is not a problem in itself.
