On that topic, I did a somewhat weird thing in C yesterday. I took code like this:

  for (;;) {
    /* original big loop */
  }

and turned it into this:

  if (compatibility_with_old_version) for(;;) {
    /* original big loop: same indentation level! */
  } else for (;;) {
    /* rewritten new loop */
  }
 

I.e.

  if (...) for (...) {

  } else for (...) {

  }

Works for me.
