Subject: [PATCH] Update 2004/sds

Updated try section (updated .gitignore for this).

Updated Makefile to let encoder.c compile (that's the generated file)
via make.

Format fixes and typo fixes.

Add INABIAF to bugs.md and the README.md file about this entry (the
generated code).

 This program is obfuscated in a number of ways:
 
-* The code is all but impossible to read due to the spacing
-* The algorithm is well hidden in the code due to copious red-herrings
-* The long expressions cause indentation tools to give poor results
-* And good old fashioned ternery operators are the icing on the cake
