reachable.c: add HEAD to reachability starting commitsmk/reachable-protect-detached-head
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. Signed-off-by: Max Kirillov <max@max630.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
