Add AppleScripts to Git repository
I recommend keeping git out of your ~/Library folders, both to keep things simple for people using your scripts, and for stability's sake (I'd argue that the Library's contents should be considered an implementation detail of OS X that you can't rely on not to change on you in future versions). 

Instead, I would just copy all the scripts in their textual form into a separate folder for the git repo (~/applescripts, for example), share that, and include instructions for where the user should install the scripts in your README file.
