Carl Worth 652fa272ea Avoid swallowing initial left parenthesis from nested macro invocation. 
We weren't including this left parenthesis in the argument's token
list so the nested function invocation wasn not being recognized.

With this fix, tests 21 and 22 now pass.

glcpp -- GLSL "C" preprocessor

This is a simple preprocessor designed to provide the preprocessing
needs of the GLSL language. The requirements for this preprocessor are
specified in the GLSL 1.30 specification availble from:

http://www.opengl.org/registry/doc/GLSLangSpec.Full.1.30.08.pdf

This specification is not precise on some semantics, (for example,
#define and #if), defining these merely "as is standard for C++
preprocessors". To fill in these details, I've been using the C99
standard (for which I had a convenient copy) as available from:

http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1124.pdf
