nano: update to 4.0

2019.03.24 - GNU nano 4.0 "Thy Rope of Sands"
	• An overlong line is no longer automatically hard-wrapped.
	• Smooth scrolling (one line at a time) has become the default.
	• A newline character is no longer automatically added at end of buffer.
	• The line below the title bar is by default part of the editing space.
	• Option --breaklonglines (-b) turns automatic hard-wrapping back on.
	• Option --jumpyscrolling (-j) gives the chunky, half-screen scrolling.
	• Option --finalnewline (-f) brings back the automatic newline at EOF.
	• Option --emptyline (-e) leaves the line below the title bar unused.
	• <Alt+Up> and <Alt+Down> now do a linewise scroll instead of a \ 
findnext.
	• Any number of justifications can be undone (like all other operations).
	• When marked text is justified, it becomes a single, separate paragraph.
	• Option --guidestripe=<number> draws a vertical bar at the given column.
	• Option --fill=<number> no longer turns on automatic hard-wrapping.
	• When a line continues offscreen, it now ends with a highlighted \ 
">".
	• The halfs of a split two-column character are shown as "[" and \ 
"]".
	• A line now scrolls horizontally one column earlier.
	• The bindable functions 'cutwordleft' and 'cutwordright' were renamed
	  to 'chopwordleft' and 'chopwordright' as they don't use the cutbuffer.
	• The paragraph-jumping functions were moved from Search to Go-to-Line.
	• Option --rebinddelete is able to compensate for more misbindings.
	• Options --morespace and --smooth are obsolete and thus ignored.
	• The --disable-wrapping-as-root configure option was removed.
