`@inheritParams` with comma-separated parameters

[ms609]

@inheritParams does not inherit any parameters whose definition is shared, via a comma, with \dots.

#' Foo
#' @param a A variable.
#' @param b,\dots Parameters to pass to `SomeFunc()`.
#' @export
foo <- function (a, b, ...) {}

# Inherits 'a' successfully.
# Does not inherit 'b' or '\dots'
#' Bar
#' @inheritParams foo
#' @export
bar <- function(a, b, ...) {}

# Does not inherit 'b'
#' Bar with own dots parameter
#' @inheritParams foo
#' @param \dots Document dots separately
#' @export
bardot <- function(a, b, ...) {}
