Carl Worth 323421db65 Remove "unnecessary" whitespace from some tests. 
This whitespace was not part of anything being tested, and it
introduces differences (that we don't actually care about) between the
output of "gcc -E" and glcpp.

Just eliminate this extra whitespace to reduce spurious test-case
failures.

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
