I see the message when the pending-deletion file list is popped
and you are asked for confirmation.  Emacs is not deleting
anything at that point.  It does not start deleting the files
until you confirm that you want to delete them.

Whether the message appears at all depends on the timing done
in `progress-reporter-do-update'.  That is the code that shows
the message.  You may or may not see the message at all,
depending on your context.
