@zachriggle: I consider this a bugfix. If you disagree, I will do a PR against dev instead.

If you think this is a valid bugfix, reply with ACK, and I will make a new release based upon it.

docs.pwnies.dk does not resolve, and I don't think has ever been the canonical docs location

[zachriggle]

No need for a new release. This only affects web-facing stuff, and is a no-op in most cases.

[TethysSvensson]

docs.pwnies.dk was a mistake.

After talking to @zachriggle, we agreed that documentation fixes goes into the earliest branch that has the mistake, but they will not trigger new releases.

Most of the logic for this is that I expect 99% of documentation use-cases are to view the documentation online, which tracks the branch, not the tag. No need to create a new tag for the documentation to update on-line.
