Interactively the current buffer's file name is the default for NEW
and a backup file for NEW is the default for OLD.
When called interactively, read OLD and NEW using the minibuffer;
the default for NEW is the current buffer's file name, and the
default for OLD is a backup file for NEW, if one exists.
If NO-ASYNC is non-nil, call diff synchronously.
