Recursion in _nc_wgetch (ncurses 5.3)

[R . Chamberlin]

You may have already found this one, but an ncurses 5.3 app 
blows up with infinite recursion in _nc_wgetch in v5.3 if you redirect 
stdin, stdout and stderr on some platforms (notably SCO and 
Unixware).

This is because of the cooked mode handling:

just after logging "filling queue in cooked mode", 
ncurses makes a called to wgetnstr - a somewhat stupid thing to 
do if wgetnstr calls straight back to wgetch.

I must admit I haven't followed the logic of why you would want to 
do this - I would guess there is some cooked mode handing in 
wgetnstr, but it seems to be broken on Sco/Unixware.

Anyway #if 0ing out the code fixes it, although I figured I should 
report the issue to you.
