There's not currently a good solution for this since each user is
editing a separate copy of the file. Sudo could try to lock the
original file and issue a warning it may already be in use if another
process already has it locked.
Matching the exact behavior of every editor is not really possible
but it could detect when the editor is vi, nvi or vim and use the
-R flag to open the session readonly.
