[PATCH] Fix bisection terminating condition
When testing bisection and using gitk to visualize the result, it was obvious that the termination condition was broken. We know what the bad entry is only when the bisection ends up telling us to test the known-bad entry again. Also, add a safety net: if somebody marks as good something that includes the known-bad point, we now notice and complain, instead of writing an empty revision to the new bisection branch.
