Reduce indentation level of big switch statement.

Browse Source 
A style thing. I find it easier to read this way.

i.e. do:

while(1) {
  if (blah) {
    ...
    continue;
  }
  ... // big switch statement
}

instead of:

while(1) {
  if (blah) {
    ...
  } else {
    ... // big switch statement
  }
}
