- Description of what previous code was doing in commit r44469 was completely incorrect.
Source prior to r44469 was only missing parentheses.
- CmpSplitLeaf: Revert back to previous code with correct fix. Fireballs code was correct,
and because I found it before him I save myself from a severe lashing.
