git-review: add gofmt command

- move gofmt invocation code from hook.go into gofmt.go
- use true branch point instead of HEAD^
- handle gofmt errors (syntax errors in Go files)
- apply gofmt command to both index and working tree, independently
- fix gofmt pre-commit hook to use index, not working tree
