This allows you to do "git clone --branch=v1.7.8 git.git" and work
right away from there. No big deal, just one more convenient step, I
think. --branch taking a tag may be confusing though.
We can still have master in this case instead of detached HEAD, which
may make more sense because we use --branch. I don't care much which
way should be used.
Like? Dislike?
