[wp-hackers] Howto exclude capital words (within URL address) from being searched and replaced?

[scribu]

You would have to not select "words" that begin with '.+://' or something.

Instead of using a filter that has to parse the content on each page load,
wouldn't it be better to add the abbr tags just before the post is saved to
the database?
