new feature: option --modernbindings sets up more widespread key bindings
With --modernbindings, ^Q quits, ^F finds, ^B finds backwards, ^G finds again, ^D finds again backwards, ^X cuts, ^C copies, ^V pastes, ^A sets the mark, ^R replaces, ^O opens a file, ^W writes out a file, ^S saves, ^Z undoes, ^Y redoes, ^P shows the position, ^T goes to a given line, and ^E executes. Note that with --modernbindings ^Q and ^S are always bound, meaning that --preserve / 'set preserve' is ignored. This is necessary because ^Q is an essential keystroke in the modern bindings. Also note that these "modern bindings" are effective only in the main edit window, not in the various menus. In all menus ^C means Cancel, and I can't think of a good alternative default keystroke for that (in order for ^C to mean Copy). And in a few menus ^V has a meaning, and there is no good alternative for that either. So... in the menus the user has to use M-6 for Copy and ^U for Paste (and ^K for Erase -- Cut does not exist in the menus), like with the default bindings.
