bug in test for multiline @export tag

[thomasp85]

When parsing and checking the tags the existence of "\n" after @export is considered equal with a multiline tag and raises a warning - the offending code is in tags$export

tags$export
function (x) 
{
    if (str_detect(x$val, "\n")) {
        tag_warning(x, "may only span a single line")
    }
    else if (!rdComplete(x$val)) {
        tag_warning(x, "mismatched braces or quotes")
    }
    else {
        x$val <- str_split(str_trim(x$val), "\\s+")[[1]]
        x
    }
}
<environment: namespace:roxygen2>

This approach means that the following oxygen comment raises a warning:

#' @export
#'
