"Special Tag Properties" interface deletes tabs and blank spaces

[blitzschlagman]

The FCKeditor/MediaWiki "Special Tag Properties" interface for adding and editing "special tags" deletes tabs and blank spaces at the beginning of the lines, i.e. when adding and editing xml-code (which contains blank spaces or tabs at the beginning of the lines).

This happens only in IE (7, 8) when a page is re-edited. No problems with Firefox.

"Extension:SyntaxHighlight GeSHi" for proper source code formatting installed.

Could you check this patch and let me know whether everything works as expected?

The SVN instructions are available here:  http://mediawiki.fckeditor.net/index.php/SVN_Instructions (the easiest solution is to use TortoiseSVN if you're working on Windows)

Unfortunately the patch could not be installed properly (got an error message).

We modified the code of the corresponding files by hand and now everything works as expected (tested with version 2.6.4 Build 21629).

We have noticed only one minor bug: With every preview of the Wiki-page a <br> is generated after the </source> tag.

Btw.: Will this patch be integraded in the extension-repository?
