[Rd] Should c(..., recursive = TRUE) and unlist(x, recursive = TRUE) recurse into expression vectors?

Reading the body of function 'AnswerType' in bind.c, called from 'do_c' and 'do_unlist', I notice that EXPRSXP and VECSXP are handled identically in the recurse = TRUE case. A corollary is that c(recursive = TRUE) and unlist(recursive = TRUE) treat expression vectors like expression(a, b)
