"He went down a treat"

Retracting his retraction Keith Richards admits that he did indeed snort his old boy's ashes.

In other Keith Richards related drugs news he is quoted as saying:

"Drugs I'm on now - the s**t I've gotta take because of the brain job, Dilantin. Means you can't take cocaine anymore...Which is fine with me. But now I can't do that anymore, so I don't do it no more. I still smoke like a fucking chimney."

What I don't understand is why they **'d out "shit" but left "fucking" in. If I weren't so lazy I ought to consult the Guardian sytle guide to find out why.
