Format/typo check + update bugs.md for 1992/vern

The bugs.md has both a feature and a bug or maybe mis-feature that might
be good to fix. I gave a tip in the bugs.md that might help with parsing
the code a bit.

The README.md file has been typo and format checked/fixed.

This should complete 1992.

+## 1992 vern
+
+### STATUS: INABIAF - please **DO NOT** fix
+### Source code: [1992/vern/vern.c](1992/vern/vern.c)
+### Information: [1992/vern/README.md](1992/vern/README.md)
+
+When your own checkmate is imminent it prints `"Har har"` but does not exit so
+it can 'rub your nose in defeat', as the author puts it. You will have to exit
+it yourself through ctrl-c or killing it in some other fashion.
+
+
+### STATUS: known bug - please help us fix
+
+If one enters a number out of range, that is < 00 or > 77, the program will
+enter an infinite loop, flooding the screen.
+
+You are welcome to try and fix this (mis)feature. It might help if you run the
+intermediate step in compilation like so:
+
+```sh
+sed <vern.c 's/{ /(/g;s/} /)/g;s/;       /#define /' | \
+    sed 's/}      /=/g;s/{        /i/g' >vern.tmp.c
+```
+
+and look at `vern.tmp.c` instead, to give you an idea of what is going on.
