Refactored patterns, added C#.

See above.

For future reference, turns out you can install the C# compiler on the Mac by running brew install mono and then you invoke it as mcs, as in mcs testme.cs.

Added a test for C#. Here's output for the C# error (correct):

---

% mcs testme.cs            
testme.cs(13,44): error CS1010: Newline in constant
testme.cs(15,12): error CS1525: Unexpected symbol `Console'
Compilation failed: 2 error(s), 0 warnings
% mcs testme.cs |& cwhy
The problem is that there is a syntax error in your code.
Specifically, on line 13, you have forgotten to close the string with
a quotation mark. The corrected line should be:

13             string message = "Hello World!!";
