From 7ecbbf877c9a0716ccccd25609b01023eecd27c0 Mon Sep 17 00:00:00 2001 From: Jay Soffian Date: Wed, 25 Feb 2009 03:32:27 -0500 Subject: [PATCH] builtin-remote: new show output style The existing output of "git remote show " is too verbose for the information it provides. This patch teaches it to provide more information in less space. The output for push refspecs is addressed in the next patch.
