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.
