Lowercase p, dangit!

How to remove the ‘capital_P_dangit’ filter from WordPress

The ‘capital_P_dangit’ is a small piece of code that was added to the WordPress core just before WordPress 3.0 was released. It changes all instances of “Wordpress” (notice the lowercase “p”) to “WordPress” in areas where content is shown on the site. The code, written by Matt Mullenweg himself, was committed to WordPress without a Trac ticket, so it wasn’t left open to community discussion beforehand.
