From b150794dafb0a7a1c5caba6fdf7d517a1a15cb59 Mon Sep 17 00:00:00 2001 From: Jacob Keller Date: Wed, 16 Jul 2014 14:48:02 -0700 Subject: tag: support configuring --sort via .gitconfig Add support for configuring default sort ordering for git tags. Command line option will override this configured value, using the exact same syntax.
