inheritDotParams can lead to multiple "..." arguments

[gustavdelius]

If @inheritDotParams and @inheritParams are both used together, one does not want to end up with two ... in the argument list. But currently

#' Foo
#'
#' @inheritParams bar
#' @inheritDotParams baz
foo <- function(x, ...) {}

#' Bar
#'
#' @param x x
#' @param ... Unused
bar <- function(x, ...) {}

#' Baz
#'
#' @param y y
#' @param z z
baz <- function(y, z) {}

produces the following argument list for foo:

\arguments{
  \item{x}{x} \item{...}{unused} \item{...}{Arguments passed on
  to \code{baz} \describe{ \item{y}{y} \item{z}{z} }}
}

The extra \item{...}{Unused} should not be there.

I am facing the same issue.
