[PATCH 1/3] Introduce i18n.commitencoding.

[Junio C Hamano <junkio@cox.net>]

This is to hold what the project-local rule as to the
charset/encoding for the commit log message is.  Lack of it
defaults to utf-8.

 * This is not needed to make the gitk patch I just sent out
   work, because git-repo-config can do its own thing without
   the C-level integration like this.

   That may or may not be a good thing, though.  I wished either
   'git-var i18n.commitencoding' or 'git-repo-config --get
   i18n.commitencoding' in a vanilla repository to emit the
   default "utf-8".  Johannes?
