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

I don't think there's anything we can do here — you have generate a valid (if unusual) roxygen2 structure. If we could go back in time, I think I'd make the rules for blocks stricter (i.e. they'd have to be before the function) but by now people rely on this and changing it would break existing code.
