@kay-kim RFM for master

My very first pull request!

Hey @steveren -- the commits include couple for the $indexStats change as well

[atsansone]

@kay-kim : I'm helping fix that.

Okay. I think this is residual effect of not doing git checkout -b upstream/master (everyone makes this mistake which means they accidentally make a branch of whatever local working branch they're on and picking up other commits).

cc: @atsansone @steveren

In your .bashrc or .bash_profile, you can put

parse_git_branch() {
  git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1)/'
}
PS1="\w\$(parse_git_branch) $ "

so that if you're on a git branch, it'll tell you what branch you're on.
