title: Remove the delay on getch() function
body: <p>i'm using ncurses in C prog and i would like to use getch() to catch arrow key and escape key.</p>
  
  <p>I use newterm, raw mode, noecho mode and keypad set to TRUE to use correctly getch.
  I can easly get the key code of arrow or either every key but when I press escape, I know getch set a timer of ~1 sec to check if none of other keys is pressed.</p>
  
  <p>Do you think the delay could be delete or set at zero ?</p>
  
  <p>Man or IBM doc said it's not useful to try to catch escape with getch when you use at the same time keypad but i would like to get it...</p>
  
  <p>Sorry for my bad english and thanks you for yours answers :)</p>
