(Emacs/config)-:pretty sections for eshell,java,c#,c/c++

Honestly not that useful for eshell (made it annoying to read text),
whereas in c/c++ it made looking at certain formatted code really
annoying.

Java and C# aren't used anyway.

In most cases, when reading code in a non terse language like C/C++,
C# or Java I'd rather just /see/ the code.  In something like Lisp or
Python the symbols just make it that much easier to read code.
