[antlr-interest] gUnit special character escaping

[Ana Nelson]

Following Andreas' example I got the multi-line expressions to work. I had
originally tried

<<
"ABC DE"
>>

rather than

<< "ABC DE"
>>

and was getting an error since I was testing a "line" rule which only
expected a single newline character but was getting 2.

I added a note about this on the gUnit Wiki page in SimpleC.testsuite.
