Thanks!

You might want to move that to korg instead, because many people don't like to 
pull from github.

So as long as you have the tested sha1 mentioned in the bug report, and that sha1 
can be pulled from somewhere on korg, I'm a happy camper: in this particular case 
it would have told me whether your testing tree had upstream fix 990486c8af or 
not.

Rebasing and applying email patches for testing purposes is otherwise perfectly 
OK, as long as the precise Git tree used for testing can be fetched.

Thanks,
