Invalid macro highlighting

[proowl]

Example:

#define LOG1(sev) \
  LOG2(sev) << "#" << " smth "

// everything further is highlighted as string literal
int f(void) {
// smth
}

But when LOG2 takes no arguments, it's ok (the same effect if remove #) :

#define LOG1(sev) \
  LOG2 << "#" << " smth "

int f(void) {
// smth
}
