How about combining the "let's make break implicit" idea with the
"lets add ranges and lists" idea and solve everybody's problems? E.g.:

ch = getch();
switch (ch) {
  case 'q','Q',27,13:
    exit_menu=1;
  case 'a':
    do_a();
  ...etc
}

Now, a break within a case can be used to break out of an enclosing loop,
and the "multi-case" capability is still maintained.
