Hide HEAD branches by default

[Turbo87]

The HEAD "branches" (HEAD, origin/HEAD, ...) are usually just adding noise to the history graph unless they are in detached HEAD mode. I would like to propose to hide the HEAD branches if there is at least one other branch pointing at the same commit.

@Turbo87 thank you for reminding me. I agree. I used to hide origin/HEAD, but if it's visible again it's probably a bug. Will have a look.

Actually [remote]/head is the only HEAD branch which can appear, right?

Please note that there is an exception when repo is in detached head state, which is a feature (more info here #107).

[Turbo87]

yeah, I saw #107 and that absolutely makes sense to me. I'm actually seeing upstream/HEAD right now, not sure about origin/HEAD, but IMHO the name of the remote shouldn't make a difference.

[Turbo87]

note that I'm using git clone --origin=upstream by default which is probably be the reason I'm seeing upstream/HEAD

This should be done in 1.0.61
