Patch 7.0.023
Problem:    Crash when doing spell completion in an empty line and pressing
	    CTRL-E.
Solution:   Check for a zero pointer. (James Vega)
	    Also handle a situation without a matching pattern better, report
	    "No matches" instead of remaining in undefined CTRL-X mode.  And
	    get out of CTRL-X mode when typing a letter.
