updated for version 7.4.242

Problem:    getreg() does not distinguish between a NL used for a line break
            and a NL used for a NUL character.
Solution:   Add another argument to return a list. (ZyX)

 		getreg('=', 1) returns the expression itself, so that it can
 		be restored with |setreg()|.  For other registers the extra
 		argument is ignored, thus you can always give it.

 		If {regname} is not specified, |v:register| is used.
