Fixes to thanks for fixes file

At least one entry was missing (1984/anonymous).

Some entries were removed. One such entry was not ever broken but
instead when I had renamed a file (to markdown) I forgot to update the
DATA variable in the Makefile which then broke compilation. This was
seen in the log and mistakenly believed that there was something wrong
with the entry when there wasn't. Other entries removed were not fixes
but notes.

Various README.md files have been updated for this sometimes just
formatting merely because I opened the file because for instance there
is an alternate version (many by me) that is referred to. I'd not be
surprised if more README.md files have to be updated for this much
better system but these will be found in time when I do another pass
(and some years I have not checked at all yet).
