Preprocessor computed include syntax busts additional highlighting

[jevolk]

There's a little known feature of GCC (and clang) called Computed Includes which is basically a way to use a #define or -D or macro value as the #include argument rather than directly using a fixed string. The manual doesn't show the best examples, but the way this tends to be used is without a closing > or basically: #include <MALLOC_H. It's quirky, but legit. Unfortunately the highlighter expects that closing > (and probably closing ") so the result is an overrun like this.
