I admit I find this a little bit strange. Since you're the person that authored
the content in here I don't know whether it's actually necessary to make this
copy and preserve the history like that.

But if you have a strong conviction, lgtm.

It's probably not a big deal in this case, but may be useful if people ever look
back via git blame... I have been asked to do this in similar situations in the
past.
