Yes, I understood that. My intention is to notify the user about the
deletion but not
really want to revert the file. Emacs provide other options other than
reverting. A
"revert" here might mean "close this buffer". However,this might need
further
modification to notify the user about the deletion instead of the normal
modification
notification. Using the original `ask-user-about-supersession-threat' might
be a bit
confusing if file is deleted. What do you think?
