Get all 1986 entries to compile

1986/wall will not compile under the default gcc (as it's actually
clang) with macOS as it requires -traditional-cpp which unfortunately
clang does not support.

Also fixed many of the README.md files.

Removed 1986/bright/bright.orig.c (probably because it won't compile on
modern systems but maybe not; I did that change a while back but didn't
finish working on 1986 until just now).

 ## Judges' comments:
 
-Compile this program and give filenames as arguments.  For example try:
-
-	./bright bright.c
-	./bright bright
+Compile this program and give a filename as an argument.
 
 Mr. Bright exploits the C pre-processor, similar variables and
 excessive shifting to obfuscate an otherwise useful binary display
 program.  This gives you a small example of what it is like to
 maintain the Bourne shell! :-}
 
-NOTE: To compile with modern compilers, you make need to: make alt.
