(And > do you still see this problem in recent Emacs versions, Chris?) Unfortunately, there was no further progress at the time. There was a great deal of C++ raw-string processing and template marking happening, although Chris told me there was no raw string in the text. I suspect the bug, whatever it was, will have been fixed since late 2018. The raw string processing has been significantly enhanced since then. So, Chris, are the problems still apparent? > -- > (domestic pets only, the antidote for overdose, milk.) > bloggy blog: http://lars.ingebrigtsen.no -- Alan Mackenzie (Nuremberg, Germany).
