That'll work, but its inefficient. p_close is called for every paragraph close, so executing a regex on the output so far, each time a paragraph is closed isn't the best.
It could make sense to check for empty para at that point, but a preg function wouldn't be the best method.
I'd move the regex up to document_end(). Its the last instruction in the wiki page instruction list. Slot in the preg_replace line in above the TOC prepending. (around #91)

This is probably a better pattern too ...
$this->doc = preg_replace('#<p(>| .*?>)\s*</p>#','',$this->doc);
