Light Documentation Issue on Clang 3.4.2

The Description for the RecursiveASTVisitor class from release 3.4 is doubled
http://clang.llvm.org/doxygen/classclang_1_1RecursiveASTVisitor.html#details

Interesting. Maybe Doxygen gets confused about the
DataRecursiveASTVisitor definition in DataRecursiveASTVisitor.h, which
looks like a copy of RecursiveASTVisitor with "#define
RecursiveASTVisitor DataRecursiveASTVisitor" before it.
