Update editors/nano to 2.8.1

2017.04.12 - GNU nano 2.8.1 "Ellert" fixes build failures on MacOS and
		on musl, fixes scrolling problems in softwrap mode when
		double-width characters on row boundaries are involved,
		shows double-width characters as ">" and "<" when split
		across two rows, moves the cursor more predictably (at
		the cost of sometimes putting it on the second "half"
		of a character), avoids creating lines that consist of
		only blanks when using autoindent, makes ^Home and ^End
		go to the start and end of the file (on terminals that
		support those keystrokes), places the cursor better when
		linting, lets the linter ask only once whether to open
		an included file, and adds bindings for ^Up and ^Down
		in the file browser.  Don't sit on your hands.

2017.03.31 - GNU nano 2.8.0 "Axat" makes it easier to move around in
		softwrapped lines: the Up and Down keys now step from
		visual row to visual row instead of jumping between
		logical lines, and the Home and End keys now move to
		the start and end of a row, and only when already
		there, then to the start and end of the logical line.
		Furthermore, the screen can now scroll per row instead
		of always per logical line.  On an entirely different
		front: nano now makes use of gnulib, to make it build
		on more platforms.  In short: there were many internal
		changes, not many user-visible ones (apart from the
		new softwrap navigation).  The conversion to gnulib
		was done by Mike Frysinger, the softwrap overhaul by
		David Ramsey.
