update: show the commit to which we updated in case of multiple heads (BC)...
update: show the commit to which we updated in case of multiple heads (BC) Currently when we have multiple heads on the same branch, update tells us that there some more heads for the current branch but does not tells us the head to which the repository has been updated to. It makes more sense showing the head we updated to and then telling there are some more heads.
