Hmm ...

Was having some problems with tab completion spitting out garbage like the
rest of my .bash_extras was being executed every time I hit tab.

Not sure what fixed it. Maybe changing quotes.
Fixed Title and Prompt

Ah .. that's better. I took the default Ubuntu PS1 (`echo $PS1`), then
dissected it until I could figure out what it does. Turns out I don't need
all the magic voodoo I was using. The magic voodoo was already there! But I
didn't see it because I had ignored it when I set my PS1 to just "$ ".

There's a piece of the default prompt that actually sets the title. And the
working directory is just "\w". Best of both worlds!
