It has been deemed that this should be okay now so we decided to add the
code.
This required a minor change in 2020/ferguson2 which I have made here as
well in this commit.
In nathan.c there was also a typo fix but since it's not the original
entry (or any thing like it) it's okay to do this. This is actually the
subject of a discussion to be had on GitHub which I'll be addressing in
a bit.
In README.md there was also a typo fixed.
We we move 1988-2004 entries from all of a year's winning entries
in a single directory to each winner being in their own sub-directory
under the given year directory.
