Fixes in thanks-for-fixes.md file

There were several fixes that needed to be made. Some were done and in
the process I discovered some fixed entries that really should be an
alternate version. That was not yet done but I have kept track of some
and will find the others - another time.

As there are more important things to do (like the jprint tool in the
mkiocccentry repo) and since I need a break I have decided to make a
pull request with the changes made.

Some README.md files had to be updated for this commit as well.
