Subject: 1.11.maint1 and clrscr

    Hello,

    I have installed 1.11.maint1 fixes and I find there still is a little bug
in clrscr (gppconio.h). It erases one char to the right from where it should.
This is because .winright starts in 1 and VIDADDR require arguments starting
from 0. This code will show the problem (the 'x' won't be erased):

main ()
{
   gotoxy (1,1);
   putch ('x');
   clrscr ();
}

The problem is bigger when clearing windows. Anyway here goes the diff to
correct the problem:
