From c40fdd01dd120c8c63da5e830ccdeb1518434bd6 Mon Sep 17 00:00:00 2001 From: Max Kirillov Date: Wed, 3 Sep 2014 19:14:10 +0300 Subject: reachable.c: add HEAD to reachability starting commits HEAD is not explicitly used as a starting commit for calculating reachability, so if it's detached and reflogs are disabled it may be pruned. Add tests which demonstrate it. Test 'prune: prune former HEAD after checking out branch' also reverts changes to repository.
