a place in goconfig misleading me

[tw4452852]

Hi,
Today, I read revel's src, and find a place in goconfig that I can't understand. Can you help me?
in goconfig/config/read.go Line93, why getting the index of "=:" twice, I think inner one is same as the outer one.

// Other alternatives
        default:
            i := strings.IndexAny(l, "=:")

            switch {
            // Option and value
            case i > 0:
                i := strings.IndexAny(l, "=:")
                option = strings.TrimSpace(l[0:i])
                value := strings.TrimSpace(stripComments(l[i+1:]))
                self.AddOption(section, option, value)
            // Continuation of multi-line value
            case section != "" && option != "":
                prev, _ := self.RawString(section, option)
                value := strings.TrimSpace(stripComments(l))
                self.AddOption(section, option, prev+"\n"+value)

            default:
                return errors.New("could not parse line: " + l)
            }
        }

I'm not sure, as I didn't write that. I would suggest asking in this project:
