Log, Branches: allow to select two refs in Branches view and immediate reveal both of them (easier diff between two tags)

A (very small) improvement for the tag-diffs:It would be great to do the following:

• Select 2 (or more) Tags
• Reveal (from context menu)
• expected:
  • Selected 2 (or more) commits are revealed
  • diffs are shown in case 2 commit are revealed
    

This would be the perfect UI for me to diff tags, especially if commits are far away from each other.
