Oops.  My Python in a nutshell didn't make this clear.  Prothon doesn't have
\" for escaped quotes.

I would think disallowing them would be ok since we already have the single
quotes in double quotes etc. method and concatenating strings.  Combining
the two features you can create any possible string while using no escaped
quotes.

   r'a double(") ' r"and a single(') in one r-string with no esc"

Does anyone have a problem with me removing escaped quotes from r-strings
for completeness and consistency?
