Fixes #13

Hello,

Thanks for the patch, and sorry for the delay in replying!

When I try this locally, $BASH_SOURCE is not set. Why might that be?

Thanks,
jml

Hi, which bash version do you use? Maybe $BASH_SOURCE is a relatively new feature.

Also, how do you run undistract.sh?
I've done that patch so long ago that I've already forgotten everything (still works in my setup though).
