I've split the patch into two.

The inflow bits remain the same as what was posted.  I can repost this
if you want.

This new patch replaces the uses of getyx with getcurx.

commit 2caa6df91fe83630faa615011a724748feee7a30

    Use getcurx in curses code
    
    As suggested by Pedro, this changes a few spots to use getcurx, rather
    than getyx.  This avoids some unused variable warnings.
