sha1_name: tweak @{-N} lookup
Have the lookup only look at "interesting" checkouts, meaning those that tell you "Already on ..." don't count even though they also cause a reflog entry. Let interpret_nth_last_branch() return the number of characters parsed, so that git-checkout can verify that the branch spec was @{-N}, not @{-1}^2 or something like that. (The latter will be added later.) Signed-off-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Junio C Hamano <gitster@pobox.com>
