Pasting 3 lines to pastebin was a waste; just inline them in your email:

case $- in
  *i*) [[ -f /etc/bash_completion ]] && . /etc/bash_completion ;;
esac

> My question then, is what exactly is this line doing?

It is seeing if you have bash-completion installed, and if so, loading it,
so that your tab-completion is more powerful.  The check for an i within
$- is to make sure your shell is interactive, as it is a waste to start
bash-completion in a non-interactive shell.
