User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20051111 Firefox/1.5

When "eval" is called in function, defined in subscript, loaded with JSSubscriptLoader, this error occurs in recent trunk builds.

Reproducible: Always

Steps to Reproduce:
1. Create two JavaScript files:
============== main.js
var loader =
Components.classes['[e-mail]/moz/jssubscript-loader;1'].getService(Components.interfaces.mozIJSSubScriptLoader);
loader.loadSubScript('chrome://application/content/test.js');
TEST();
==============
============== test.js
function TEST()
{
  dump("EVAL: " + eval("1 + 1;") + "\n");
}
==============
2. Load "main.js" into XUL file with <script/> element.
3. Get this error in JavaScript console.

Actual Results:  
"function eval must be called directly, and not by way of a function of another name" error.

Expected Results:  
EVAL: 2
dumped into console.

Attachment: Innerize the global object

Walking up the parent chain outerizes the global object (wrongly). We need to innerize at the top so that the script is loaded with the correct parent chain (pointing at the inner chrome window).

 Patch works for me (reporter) on very recent trunk build (updated from CVS about 06 Dec 2005 22:00 GMT+3).

Shaver gave me r=him in person. I also fixed the fprintf to print the correct thing.

Fix checked in. Nominating for branches since this is a relatively large regression from 1.0.x.
