sp_techniques clarity

[Dave Abrahams]

http://www.boost.org/doc/libs/1_35_0/libs/smart_ptr/sp_techniques.html#preventing_delete seems to suggest that the private deleter is what prevents "delete p.get()", but in fact it's the private dtor that does the trick. It's not entirely clear what you're trying to illustrate here but whatever it is, I think it could use a little more explanation.

If the deleter isn't also private then it doesn't solve the problem, as X::deleter()( p.get ); will still work.

The way I read it, that particular example is showing a technique using a private deleter. Yes, it relies on a private dtor, but the deleter and the fact it's private are the key points.
