Merge remote-tracking branch 'origin/master' into 5.9

* Test/D02glob.ztst:
  On the "unreadable directories can be globbed (users/24619, users/24626)"
  test, resolve conflicts by removing the Cygwin-only skip that has been added
  in master, since the test is passing on this branch.  This effectively reverts
  workers/45492.  See discussion starting in workers/45504.
