Re: backing store, and documentation

["Raul D. Miller" <moth@debian.org>]

Here's a documentation patch based on my experimentation.

Note: if I got anything wrong, that's reflected here.  In particular,
I'm bothered that Option BackingStore didn't work in the ServerFlags
section -- I suspect that's either a mistake on my part or a bug in
the implementation.  [I'd go back and test, but I've been up all night
and I need some sleep.]

Thanks,
