XEmacs is stuck with it (backward compatibility with user code, as in practice a lot of users are dependent on 21.5 features that we've refused to backport, we can't really get away with saying "you knew it was a beta"). If there's a better alternative (which I'm not sure there is), Emacs has no backwards compatibility problem, and no XEmacs compatibility problem either. > Is XEmacs going to run into the same problems when ingesting some of > Emacs' highlighting/parsing stuff? Technically, yes. I don't expect to see a lot of real-world code that uses rawstrings that end in "\", though, so we can just document this wart (or document that #r rawstrings that end in "\" have undefined behavior). But why should Emacs put up with such a wart?
