From 8d646a9bac7d64c38060e0c252fd87eba6c4d5cf Mon Sep 17 00:00:00 2001 From: Krzesimir Nowak Date: Wed, 11 Dec 2013 12:54:43 +0100 Subject: [PATCH] gitweb: Add a feature for adding more branch refs Allow extra-branch-refs feature to tell gitweb to show refs from additional hierarchies in addition to branches in the list-of-branches view.
