I finally took the plunge and upgraded WordPress to 1.5.1. That necessitated finding the little hacks I put in. In particular (I'm writing this here so I can find it next time), in wp-include/default-filters.php, I remove the wpautop from the_content and the_excerpt. This causes these pages to be displayed with the html in them. Could be dangerous but the html is filtered when it's entered so the problem is minimal. Someday I'll submit a change that will allow specifying whether the comment should be formatted. This was one feature I really missed from MovableType -- the ability to mark individual entries with a format or not flag.

Anyway, I'm upgraded so now I get to figure out how to handle all these new features.
