In parse.y, around line 435 and before: no check is made to see if 
readline returns EOF, which it will when you type ctrl-D to exit.  The
result is that the strlen on line 435 induces a segmentation violation
and core dump.

Also, the first character typed after the prompt is overwritten by
a backspace and then character is retyped:  why???
