Nesting in else clauses is sometimes parsed incorrectly

[mayshukla]

The following is parsed incorrectly:

int main() {
  int i = 0;
  #ifdef A
    i++;
  #else
    #ifdef B
      i--;
    #endif
    i--;
  #endif
}

It's parsed as:

int main() {
    int i = 0;
    #ifdef A {
        i++;
    } #else {
        i--;
        i--;
    }
    #endif
}
// In context: True

Note that #ifdef B surrounding the first i--; was ignored. This problem only occurs when #ifdef B is the first statement in the else clause. Also, it is parsed correctly when it is in the then clause.

Update: I fixed this issue. Now when the parser encounters a split token at the beginning of a variant statement, it checks to see if it should split there (instead of t just skipping the split token).
