Update FAQ about incongruent code & author remarks

As I was looking at 2004/burley/README.md it occurred to me that
numerous entries have been modified in ways that are incongruent with
what the author(s) originally wrote about the entry. In some cases this
has been noted in the README.md file (like has been added to
2004/burley/README.md itself) but not in all. That should probably be
checked for and I will do that in time most likely but in the meantime
it felt even better to update the FAQ about this which this commit does
as well.

+It is very likely in this case that the code was fixed to work for modern

+some entries you should look at the original code as in `winner.orig.c` or
