/**
* Replaces double line-breaks with paragraph elements.
*
* A group of regex replaces used to identify text formatted with newlines and
* replace double line-breaks with HTML paragraph tags. The remaining
* line-breaks after conversion become <<br />> tags, unless $br is set to '0'
* or 'false'.
*
* @since 0.71
*
* @param string $pee The text which has to be formatted.
* @param int|bool $br Optional. If set, this will convert all remaining line-breaks after paragraphing. Default true.
* @return string Text which has been converted into correct paragraph tags.
