That's not true.  AFAICT, quoting resp. escape rules haven't changed
at all, with a single exception: the old code did not support
multi-line variables, i. e. variables containing newline characters.

I don't think this has seen much (if any) testing lately, so it is well
possible that there are bugs there...
