patch 9.0.0826: if 'endofline' is set CTRL-Z may be written in a wrong place

Browse Source 
Problem:    If 'endofline' is set the CTRL-Z may be written in the wrong
            place.
Solution:   Write CTRL-Z at the end of the file.  Update the help to explain
            the possibilities better. (Ken Takata, closes #11486)
