Nathan & I hopped on a call to "pair program" on this. Given the point 
that his patch had been available on the list for awhile with limited 
public comments to date, we did the following:

* Kept everything except EXPLAIN enhancements and conflict logging. For 
the former, a lot of this wasn't in the default EXPLAIN path. For the 
latter, this was to respect the time period of the discussion.

* Did some minor wordsmithing and linking to help with overall 
accessibility, including Erik's typo catch.

Many thanks to Nathan for pulling this together. Please see v3. Feedback 
welcome.

Thanks,

Jonathan
