Changes (by vorner):

 * owner:  vorner => muks


Comment:

 I believe it would be more readable to explicitly break out of the loop
 there than rely on the side-effects and influencing the next iteration. Or
 at least putting the explanation into a comment there. But I'll leave it
 up to you.

 I think it is ready for merge (with or without the change).
