Bug 74529 [Encoding] Encoding on properties no longer explains encoding
I200409212000 This is a regression from previous builds (e.g. 3.0): along with the encoding on the properties dialog there was an explanation where it came from, e.g. inherited from container, detected from file content. This important information has gone.
