InlineEditBox: Save button not disabled after pressing Esc to revert value.

[ptbrunet]

Open http://archive.dojotoolkit.org/nightly/dojotoolkit/dijit/tests/test_InlineEditBox.html

Tab to and open the inline with text "refrigerators", enter text, press Esc, the Save button is not disabled; it takes one more Esc to disabled it.

Fails in FF2, FF3, IE6, IE7.

The _onKeyPress in InlineEditBox?.js is not called during ESC key processing since the key is eaten with dojo.stopEvent.

I also noted that the Save button is initially enabled even tho nothing is changed.

Fixed in [11857] (but I made a typo in the checkin comment, referring to a different bug number).
