overrideMimeType in GM_xmlhttpRequest doesn't work

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Send GM xhr with overrideMimeType: "charset=x-user-defined".
2. Send GM xhr without overrideMimeType.
3. The returned responseText is the same.

This is also an issue in Blank Canvas, so I don't know if this is a bug in the 
Chrome extension API or what, but this makes it impossible to request unencoded 
binary files, since the default encoding corrupts them. It apparently works in 
normal xmlhttpRequests:
