It seems one way to do this is to send a Device Status Report (DSR) sequence,
and to check whether the Cursor Position Report (CPR) has arrived on stdin...

i.e., send a "\0x1b[6n", and read a "\0x1b[%d;%dR", line, column.  There is
little chance that the user will type in exactly that at the right time, don't
you think ?
