Michael means that git has no "branch" concept, only "branch head" concept.

Suppose that you have two branches, "master" and "stdenv". As usual, you 
merge master->stdenv every day or two and you merge stdenv->master every 
month or two. Then it is not possible to search for commits that first 
appeared in stdenv.
