[Buildroot] [PATCH v2] package/mg: new package

[Joachim Wiberg]

Mg is a small Emacs-like editor with no external dependencies except a
standard C library.  It weighs in at 130 kiB and is one of a select few
completely free (public domain) text editors suitable for small and
embedded systems.

This version is based on the OpenBSD Mg, but with more features, one of
which being the no-ncurses/termcap support, which heavily reduces the
impact on a resource constrained system.

+
+	  Mg is a MicroEMACS clone with the goal of being compatible
+	  with GNU Emacs, because there should never be any reason to
+	  learn more than one Emacs flavor.
+
+	  Unlike many other editors it does not require ncurses, only a
+	  standard C library, making it suitable for really small and
+	  embedded systems.
+
+	  This version is based on mg2a from OpenBSD, with more features
+	  and, in particular, no requirement on ncurses or termcap.
