Whether it's a while loop or a foreach loop, whenever I find myself
wanting to do what you're asking about (iterate from a midpoint in the
loop), I rewrite the code so it doesn't, unless it's some tiny one-off. I
hate what that does to the topology of my program and how much harder it
makes it to read.
In an application like this one, it generally signifies that I should be
parsing the whole file as a single string, or reading it in in larger
chunks than a single line.
