No, filenotify.el handles them as they are. The only change in the event
flow is, when two consecutive deleted+created events are combined to a
renamed event.
However, as said I have extended the test case a little bit. There are
now set-file-times and set-file-modes calls, which shall result in
attribute-changed events. And those events shall be suppressed, because
we start file notifications with (file-notify-add-watch ... '(change) ...)
How does w32notify report attribute changes? Could you, please, call
(trace-output 'file-notify-handle-event) and rerun file-notify-test02-events?
Best regards, Michael.
