As you add more loops with explicit 'I' counters, I wonder if we can create some helper class whose purpose is to wrap an iterator and offer a counter automatically. Something like:

for (auto line : iteratorWithIndex(lines) {
    if (line.index() > 1)
        ...
}

Or:

for (auto line : countedIterator(lines) {
    if (line.counter() > 1)
        ...
}

Hmm, this is the only case in this patch where I added an 'i' counter it seems. Also, I think in this particular instance, I could probably replace this counter by a simple boolean.
