Bug:
	bash crashes if ^D is input

Repeat by:
	1) Start up bash
	2) Type ^D

Comments:
	The problem is in yy_readline_get() in line 430 of parse.y,
	on the call to readline().  Readline() returns -1 on EOF, but
	this is not checked for, and the -1 is later passed to
	strlen() on line 435.  Instant death.  I don't have a clue
	as to how to propagate this back up gracefully, but I'm
	sure you do.  Hope this helps.
