This is called the upstream branch. Go to any branch, and do this:

% git checkout feature
% git branch --set-upstream-to master

And it would set:

  remote = .
  merge = refs/heads/master

Now you can do things like:

% git log feature@{upstream}..feature

Which gets translated to:

% git log master..feature

And:

% git rebase -i

Which gets translated to:

% git rebase -i master

This is nothing new.
