# restore control-z functionality of interactive cscope.
# version 15.6 (and previous) had control-z functionality because 
# the terminal was in cbreak mode.  Putting the terminal in raw mode
# fixed using control-c to change the 'ignore case mode'.
# catch the control-z and send ourself the suspend signal.
