bisect: new command to extend the bisect range (issue2690)

When bisect ends in a merge point, and one of the parent wasn't checked,
this usually means the culprit is in a branch that wasn't scanned.
For this case we provide a new command which extends the range of the bisect
search to the common ancestor of the parents of the merge.
