Update Emacs configuration
Update emacs.samples with new configuration snippets that match pgindent et al. formatting more accurately and follow Emacs Lisp best practices better. Add .dir-locals.el with a subset of that configuration for casual editing and viewing. Reviewed-by: Dimitri Fontaine <dimitri@2ndQuadrant.fr> Reviewed-by: Noah Misch <noah@leadboat.com>
