Reformat SEE to better document the function This is one of the most difficult to understand but also most important and speed critical functions of SF. This patch rewrites some part of it to hopefully make it clearer and drop some redundant variables in the process. Same speed than master (or even a bit more). Thanks to Chris Cain for useful feedback. No functional change.
