At the start of a rebase, ORIG_HEAD is updated to the tip of the branch being rebased. Unfortunately reset_head() always uses the current value of HEAD for this which is incorrect if the rebase is started with "git rebase <upstream> <branch>" as in that case ORIG_HEAD should be updated to <branch>. This only affects the "apply" backend as the "merge" backend does not yet use reset_head() for the initial checkout. Fix this by passing in orig_head when calling reset_head() and add some regression tests. Signed-off-by: Phillip Wood <phillip.wood@dunelm.org.uk> Signed-off-by: Junio C Hamano <gitster@pobox.com>
