If I delete a file which is opened in NEdit, I get a
warning dialog once the document is focused again. The
dialog offers three choices; until today, I *always*
wanted to use the fourth choice, "Close Document".
It's a usability debacle: Every time the user deletes a
file he has either to think of telling NEdit beforehand
or he has to Cancel this dialog, then close, then
dismiss the upcoming dialog, just to do nothing.
OTOH, Re-save can be done with Cancel, then Ctrl-s.
Save As is of dubious use, as the user would probably
moved the file in the first place if that's what he
wants. (Cancel, then Save As is of course possible.)
