----------------
I'm not too fond of all the extra scopes, dunno what others think.

If this could be implemented too look like:
```
WithColor(OS, syntax::Address) << format("\n0x%8.8x: ", Offset);
```
I think I'd prefer that (not sure if just adding a conversion operator from WithColor to raw_ostream would do the trick).
