------- Additional Comments from Michael Saboff <msaboff at apple.com>
Cleaned up both style issues pointed out.

Added code to properly handle expressions like /^a/ to only execute once and
never loop.

Found and fixed issue for expressions like /(?!^)a/ which should not be marked
as starting with a BOL, since they start with NOT BOL!
