We need to call DoRemove() on all watcher objects to really remove them, just removing our record of them was not enough and e.g. resulted in errors if we tried to re-add a previously watched path again. Closes #15531. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@76187 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
