From b2c851a8e67da752d8a5dbde5a9dae6e3428a4c9 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Tue, 20 May 2014 14:18:11 -0700 Subject: Revert "Merge branch 'jc/graduate-remote-hg-bzr' (early part)" Instead of showing a warning and working as before, fail and show the message and force immediate upgrade from their upstream repositories when these tools are run, per request from their primary author.
