Inheriting from other packages can create broken links

[karawoo]

When using @inheritDotParams to inherit documentation from another package, any links in the documentation to other functions in that package will broken. A reprex:

library("roxygen2")
roc_proc_text(rd_roclet(), "
  #' Title
  #'
  #' @inheritDotParams maps::map database
  wrapper <- function(...) maps::map(...)"
  )
#> $wrapper.Rd
#> % Generated by roxygen2: do not edit by hand
#> % Please edit documentation in RtmpentfmJ/file11179684a1b94
#> \name{wrapper}
#> \alias{wrapper}
#> \title{Title}
#> \usage{
#> wrapper(...)
#> }
#> \arguments{
#>   \item{...}{Arguments passed on to \code{maps::map}
#>   \describe{ \item{database}{ character string
#>   naming a geographical database, a list of \code{x},
#>   \code{y}, and \code{names} obtained from a previous
#>   call to \code{map} or a spatial object of class
#>   \code{SpatialPolygons} or \code{SpatialLines}.
#>   The string choices include a \code{\link{world}}
#>   map, three USA databases (\code{\link{usa}},
#>   \code{\link{state}}, \code{\link{county}}), and more (type
#>   \code{help(package='maps')} to see the package index).
#>   If the requied database is in a different package that
#>   has not been attached, the string may be started with
#>   "packagename::". The location of the map databases may be
#>   overridden by setting the \code{R_MAP_DATA_DIR} environment
#>   variable. } }}
#> }
#> \description{
#> Title
#> }

Things like \link{world} should be \link[maps:world]{world} to pass R CMD check.

Fixing this will require walking the Rd tree, looking for link objects. IIRC link works different based on the number of arguments, so the fix would just be to insert the source package name as the first element if length 1.

This would need to happen in topic_params.Rd().
