Boris Feld <boris.feld@octobus.net> [Sun, 08 Oct 2017 21:42:32 +0200] rev 34734
devel-warn: add 'warn-' to 'devel.empty-changegroup' config
Rename 'devel.empty-changegroup' to 'devel.warn-empty- changegroup' in order
to clarify it controls a warning message.
No alias is installed since the previous configuration option was not
documented.
