Netscape 7.1: URL portions in links are replaced with $5

[dustball]

1. Download Netscape 7.1 @ ​http://www.oldapps.com/netscape.htm

2. Load editor at ​http://www.fckeditor.net/demo or ​http://klug.pbwiki.biz/FCKeditor/2_4/_samples/default.html

3. Switch to source mode

The HTML has been corrupted:

<a href="http://www.fckeditor.net/$5">FCKeditor</a>

If you switch back to normal mode, and back again, it will keep adding $5$5. Sometimes, it will add $4 to the beginning of the URL and similar bugs.

The problem is in the ProtectUrl:

	ProtectUrls : function( html )
	{
		// <A> href
		alert(html);
		html = html.replace( FCKRegexLib.ProtectUrlsA	, '$1$4$2$3$5$2 _fcksavedurl=$2$3$5$2' ) ;
		alert(html);

		// <IMG> src
		html = html.replace( FCKRegexLib.ProtectUrlsImg	, '$1$4$2$3$5$2 _fcksavedurl=$2$3$5$2' ) ;

		return html ;
	},

Fixed with [210]. The Netscape 7.1 regex engine is a little bit buggy, so I have reviewed the regex (and as a plus, simplified and optimized it).

By the way, the technology (Gecko) in Netscape 7.1 is quite old and buggy. I'm not sure will compatible with that old browsers with FCKeditor 3.0.
