Hmm, I didn't notice that. I really don't like to see braces in
else clauses, without also seeing braces in the if, and have
been fixing this to add braces whenever I come across it. IMHO
the hacking guideline should only allow

  if (foo)
    bar;
  else
    wizz;

Or

  if (foo) {
    bar;
    ...
  } else {
    wizz;
    ...
  }
