Roxygen fails to parse commented code that are between single quotes

[ColinFay]

Describe the bug

If I have the following code with single quote and a comment :

#' @import shiny
this <- function() {
  c(
    'this',
    #'this',
    'this',
  )
}

roxygen2::roxygenize() will produce the following NAMESPACE:

# Generated by roxygen2: do not edit by hand

import("this',")
import(shiny)

Expected behavior

The commented code inside the function body is not added to the NAMESPACE
