// TODO: Implement some sort of git integration
// Maybe use go-git
// Specify a -git flag
// If we are operating with git then:
// Inmitialize a repo if one doesn't exist (try to open right?)
// For each file matched by glob first figure out if it's already tracked
// If not tracked then track it and commit (either it alone or maybe multiple together somehow)
// Then reset the file (to undo previous modifications)
// THEN change the file
// In addition add a -undo flag that will ONLY reset the files without changing them
// Only for the ones matched by glob
// ^ important because binary files would fuck us up
