2) Ignoring local changes to file:
git update-index --skip-worktree $FILE

// How should I write my AddFoo extension method to support this?

--This script MUST be named "Switch to <User>.scpt", where <User> is the name of the user to switch to.
--You must first make a password item (a.k.a. a key) for the other user's password using Keychain Access, 
--and call it "<user>", where "<user>" is the other user's name.the field "Kind" must be  "User Login" (without quotes). 
--The script assumes that you make this key in your login.keychain, which is the default one.
--The first time you run this script, you will be prompted to allow Keychain Scripting to access the password of the key.
--This script requires "Enable access for assistive devices" to be enabled in the Universal Access system preference pane.

set username to word -1 of my findReplace(".scpt", "", (path to me as text))

-- Invoke Fast User Switching. The `id -ur username` part gets the uid number that corresponds to the username and substitutes it at the end of the CGSession command
