It seems to behave strangely here:  I can delete the prompt, and if I
move the cursor to the left and delete some characters, the characters
to the right of the cursor don't move.  Also, the backspace key doesn't
work, although C-Backspace does work (backspace works fine with
readline).  This is in an xterm; in a cygwin shell window different
strange things happen.
