Miller,

I can understand you. You don't want to break your git history
(blame). But when a code is clearly more readable/understandable you
must assume that it has a huge net-positive.

The patch improves the code in three ways:
- Only one if/else;
- Not blame on static analysis tools.
- And avoid more discussion about that in the future (nobody will send
patches like this to disturb you about that part of code).

The decision is yours.

Thanks again.
