Nice, just a basket of nits. Big picture, looking good.

nit: this is a good candidate for a pure function that could be made visible for testing.

I'll give this some thought. Available options for testing the functionality are abstracting the input file stream, providing a fake file system implementation, or writing to the /tmp file system, none of which are very attractive.

<light hearted rant follows, feel free to ignore it since it isn't a huge deal>
I'm not suggesting writing tests per say, just suggesting that factoring out pure functions (ignoring the filesystem) makes them more testable and by extension more maintainable since they are able to be executed in isolation and the contract of input versus output is more clear than a method (who can touch any instance variable, thus having less encapsulation).
This one was so close to being a static function I thought I'd mention it in my Quixotic quest to make our codebase more Functional.

It's a good cause. I shuffled things around a bit. I was gloomy at first since I didn't want to abstract out the file system, but I found a way around it.
