	* htmlwrap -- Safely wraps a string containing HTML formatted text (not
	* a full HTML document) to a specified width
	*
	*
	* Requirements
	*   htmlwrap() requires a version of PHP later than 4.1.0 on *nix or
	* 4.2.3 on win32.
	*
	*
	* Changelog
	* 1.7  - Fix for buggy handling of \S with PCRE_UTF8 modifier
	*         - Reported by marj
	*
	* 1.6  - Fix for endless loop bug on certain special characters
	*         - Reported by Jamie Jones & Steve
	*
	* 1.5  - Tags no longer bulk converted to lowercase
	*         - Fixes a bug reported by Dave
	*
	* 1.4  - Made nobreak algorithm more robust
	*         - Fixes a bug reported by Jonathan Wage
	*
	* 1.3  - Added automatic UTF-8 encoding detection
	*      - Fixed case where HTML entities were not counted correctly
	*      - Some regexp speed tweaks
	*
	* 1.2  - Removed nl2br feature; script now *just* wraps HTML
	*
	* 1.1  - Now optionally works with UTF-8 multi-byte characters
	*
	*
	* Description
	*
	* string htmlwrap ( string str [, int width [, string break [, string nobreak]]])
	*
	* htmlwrap() is a function which wraps HTML by breaking long words and
	* preventing them from damaging your layout.  This function will NOT
	* insert <br /> tags every "width" characters as in the PHP wordwrap()
	* function.  HTML wraps automatically, so this function only ensures
	* wrapping at "width" characters is possible.  Use in places where a
	* page will accept user input in order to create HTML output like in
	* forums or blog comments.
	*
	* htmlwrap() won't break text within HTML tags and also preserves any
	* existing HTML entities within the string, like &nbsp; and &lt;  It
	* will only count these entities as one character.
	*
	* The function also allows you to specify "protected" elements, where
	* line-breaks are not inserted.  This is useful for elements like <pre>
	* if you don't want the code to be damaged by insertion of newlines.
	* Add the names of the elements you wish to protect from line-breaks as
	* as a space separate list to the nobreak argument.  Only names of
	* valid HTML tags are accepted.  (eg. "code pre blockquote")
	*
	* htmlwrap() will *always* break long strings of characters at the
	* specified width.  In this way, the function behaves as if the
	* wordwrap() "cut" flag is always set.  However, the function will try
	* to find "safe" characters within strings it breaks, where inserting a
	* line-break would make more sense.  You may edit these characters by
	* adding or removing them from the $lbrks variable.
	*
	* htmlwrap() is safe to use on strings containing UTF-8 multi-byte
	* characters.
	*
	* See the inline comments and http://www.greywyvern.com/php.php
	* for more info
