SuperClean plugin returns just quotation when executed on localhost

[Mark]

When running the SuperClean? plugin from a localhost environment the editor content gets deleted and a quotation mark is inserted instead.

The SuperClean tidy handler tries to call tidy locally before submitting the content to a remote server to do the tidying.

I suppose you have passthru() not disabled in your php.ini, and you have not installed tidy.

I propose this not very elegant fix

Index: tidy.php

       $content = ob_get_contents();
     ob_end_clean();
 
-    if(!strlen($content))
+    if(strlen($content) < 4)
     {
       // Tidy on the local machine failed, try a post
       $res_1

Any better ideas welcome, I have no experience with passthru() and such

note:

1.
if($is_windows){

passthru( ... " | tidy ... 2>nul");

}

2.
$is_safe_mode = ini_get("safe_mode");

in rev [767] I applied the patch I proposed in my comment above, though I have the strong feeling that it could be done better...
