exit without saving

Feature request:

   Meta-T  -  toggle -t / --tempfile command line option

or

   At the write file prompt, allow a control key to exit
   without saving, e.g. ^X or ^Y.

The goal is to make it easier to exit a 'nano -t' session without saving, e.g. 
as I often need to do when I press ^X and suddenly get a write file prompt 
because I'm not a user with permission to edit the file given on the command 
line. (I realize I could tell nano at that point to write to /dev/null, but it 
would be better to have a key combo that would exit without saving.)

This was asked about by someone in 2004, as well:
