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?
