I answered this (closed) question recently. I posted what was admittedly a short answer:
I think you want
However, that was essentially all the asker (thought they) needed, and I believe they accepted it.
I came back earlier to see that answer had been converted to a comment. I don't have any complaint about this, but if seems a little odd for this to happen to an accepted answer. Does it make sense for this to happen? Is a question with no accepted answer better than a question with an accepted but brief answer?
