The result of this change should be simplified to S_IWUSR | S_IRUGO.

This line is 97 columns long.

The result of this change should be simplified to S_IWUSR | S_IRUGO, and that might put it under 80 columns.  There are bound to still be other places where this kind of replacement will require additional changes to code formatting.
