lite/splitter/result.go:76:15: should use time.Since instead of time.Now().Sub (S1012)
lite/splitter/state.go:433:25: should omit comparison to bool constant, can be simplified to !copyCommit (S1002)
lite/splitter/utils.go:13:25: should use raw string (`...`) with regexp.MustCompile to avoid having to escape twice (S1007)
lite/splitter/cache.go:90:17: func (*cache).reverse is unused (U1000)

the results git subsplit created.
