q argument of sQuote() and dQuote()

[jennybc]

I recently ran into this backwards compatibility problem.

sQuote() and dQuote() gained the explicit q argument in R 3.6.0.

https://github.com/wch/r-source/blob/2c65d3d6bf25af0a3078639604feb280e69e1e46/doc/NEWS.Rd#L727-L729

sQuote() and dQuote() get an explicit q argument with obvious default instead of using getOption("fancyQuotes") implicitly and unconditionally.

Fixed in cc4846e.
