We have failed test on master branch.
```
--- FAIL: TestFormatLogMessage (0.00s)
logger_test.go:24: unexpected result; got
"foo: abcde, \"foo bar baz\", xx"
want
"foo: a..e, \"f..z\", xx"
```
if failed because maxArgs maxLen <= 4 in the `LimitStringLen` in that case we always will return the income string
but in the test we limit the maxLen by value 4
```
f("foo: %s, %q, %s", []interface{}{"abcde", fmt.Errorf("foo bar baz"), "xx"}, 4, `foo: a..e, "f..z", xx`)
