Ummmmm, hook location strip_bbcode:
PHP Code:
$fast_and_dirty = true;
I'm honestly not sure if that will do exactly what you want but it's worth trying. Did you go find the function in the file that I mentioned? Take a look at it and how it defines the parameters, like these defaults:
$stripquotes = false
$fast_and_dirty = false
$showlinks = true
$stripimg = false
$keepquotetags = false
So, try setting those to what you want and see what happens.
