If more extensive edits are needed, there's full context so you can at least flag those in the review as well.

The wording on whether or not strlcpy and strlcat will provide NULL termination is also inconsistent, hence my comments about it last weekend.  I’m going to revert all of this back to and including r367075, since Stefan wants to do this a totally different way.  Sorry for the noise everyone and thanks for the help, I learned a lot through this process.
