Hi!

I have an idea. If you do this when you make the symbolic link:
ln -s "${dot##$HOME/}" "${home_dot}"
You can use a relative path when the repo is in user's home. It's more elegant than use the full path in symbolic links.

Hi Oscar,

I commited the change that you proposed, now it's in public gist :)
