Update bugs and thanks for 1992/lush

I also removed a -Wno- option from the Makefile as the entry relies on
this warning. This is not strictly necessary as the script that I added,
runme.sh, directly compiles it, but it felt like it shouldn't have it
anyway.

In the bugs.md file I gave some hints as to why this does not work with
clang.

In the thanks file I broke up a paragraph into more than one paragraph.

 Unfortunately due to the way the entry works and the fact that other compilers
 like clang have different warnings and errors this simply does not work with
-them. Can you help us?

+Some tips from Cody:
+
+This entry relies on specific compiler warnings. With gcc it will look something
+like:
+
+```

+lush.c: In function 'main':
+lush.c:40: warning: "f" redefined
+   40 |           main
+      |
+lush.c:1: note: this is the location of the previous definition

+```
+
+Now one can use `sed` to get the `warning:` line correct but there is more to it
+than that. For instance this is what it looks like with clang:
+
+```
+lush.c:40:9: warning: 'f' macro redefined [-Wmacro-redefined]
+#define f 001:
+        ^
+lush.c:1:9: note: previous definition is here
+#define f 000:
+        ^
+lush.c:42:9: warning: 'f' macro redefined [-Wmacro-redefined]
+#define f 100:
+        ^
+lush.c:40:9: note: previous definition is here
+#define f 001:
+        ^
+```
+
+As you might see the part under the `warning:` line is different.
+
+Can you help us?
