[Rd] formals assignment now strips attributres

[Patrick Burns]

The assignment form of 'formals' strips attributes (or something close
to that) from the values in the list.  This wasn't intentional, was it?

The current behavior (2.0.0 through 2.1.0 on Windows at least):

> fjj <- function() x
> formals(fjj) <- list(x=c(a=2, b=4))
> fjj
function (x = c(2, 4))
x

Previous behavior:

> fjj <- function() x
> formals(fjj) <- list(x=c(a=2, b=4))
> fjj
function (x = structure(c(2, 4), .Names = c("a", "b")))
x
