c-to-c breaks with multiple pragma in if/for/while without compound statement

[ldore-ks]

When parsing, then generating C, the following code:

int glob = 0;
void f(int test) {
  if (test)
    #pragma clang foo
    #pragma clang bar
    glob += 1; // <-- Only increment glob if test is not false
}

Gets transformed to:

int glob = 0;
void f(int test) {
  if (test) {
    #pragma foo
    #pragma bar
  }
  glob += 1; // <-- Always increment glob
}

Source input and output have different runtime behavior.
