For eg.: https://bitbucket.org/USER/REPO/commits/HASH I see:
**USER commited HASH
and on the right:
parent commit HASH**
i think it could be great to display the branch to which that commit belongs. for me it's very important since i can't identify, unless i see the commit in the commits list (https://bitbucket.org/USER/REPO/commits/all) which says to which branch it belongs to.
