Update editors/nano to 2.7.2

2016.12.12 - GNU nano 2.7.2 "Shemesh! Shemesh!" brings another feature:
		the ability to complete with one keystroke (^] by default)
		a fragment of a word to a full word existing elsewhere in
		the current buffer.  Besides, this release fixes two bugs
		related to using line numbers in softwrap mode, allows to
		use the PageUp and PageDown keys together with Shift on
		VTE-based terminals, stops the help lines from flickering
		during interactive replacing, makes a "set fill" override
		an earlier "set nowrap", properly restores the selected
		region after an external spell check, and improves a few
		other tidbits.  If you should find any more bugs, please
		run 'man nano | grep bugs' and report them there.
