These routines delete the character under the cursor; all
characters to the right of the cursor on the same line are
moved to the left one position and the last character on
the line is filled with a blank. The cursor position does

not change (after moving to <EM>y</EM>, <EM>x</EM>, if specified). (This

does not imply use of the hardware delete character fea-
ture.)
