I accidently posted this question on stackoverflow and got a good answer there; it wouldn't be fair toward the answerer to delete it. It is already closed, but I think it would still be good to have it here on "English" territory.
I have migrated the question. In general you should flag for moderator attention on the site that the question was originally asked on, for three reasons:
- Moderators can only migrate away from their site rather than to it.
- Normal users who vote to close the question can migrate between some sites but not between Stack Overflow and English Language & Usage.
- Flagging for moderator attention will alert even moderators who do not check the meta sites often.
Administrators of this site do not have the necessary permissions to migrate questions from SO to here. It would have to be done by one of the site developers.
