Hi

In my repo I have to branches, 

    -  the default

    -  the branch Uwe.

However I just realized that

 hg log -G

Gave me

 o  changeset:   68:1ec5162467a7
| |  branch:      Uwe
| |  branch:      default/Uwe
| |  parent:      66:ce46517fd6e4

| |  date:        Mon Nov 28 12:13:06 2016 +0000
| |  summary:     Typos

What the heck is the branch
default/Uwe
