What is it supposed to do? Do you want to check that s is at least 1 character long? Otherwise it's a NOP, AFAICS.
It was supposed to check if the first character was not '/', but for some reason it was always taking the if branch.
A similar one is while (x); doSomething();Which is nearly impossible to see, and I do all the time by accident. Thankfully the compiler catches that one for us.
