nano: update to 2.9.4

2018.03.08 - GNU nano 2.9.4 "Isabel" allows binding a key to a string
             (any piece of text and/or commands), permits customizing
             the color of error messages with 'set errorcolor', colors
             those error messages by default in bright white on red,
             makes <Enter> at the bottom of the screen scroll just one
             row when --smooth is used, does not fail when redoing a
             file insertion, and cancels a Shift-selection when any
             cursor key is pressed without Shift even when the cursor
             cannot move.  Further, it treats tabs fully the same as
             spaces when doing automatic hard-wrapping, allows syntax
             names to be unquoted, and removes two deprecated options
             and six deprecated bindable function names.
