[chef] Re: Re: precedence is different, so why are values merged

[bradford < >]

I am still a little confused.  Perhaps someone could improve the docs
a bit?  More clarification is needed on when merging takes place.  Is
it always, unless you specify "!merge:"?  How do the
default_attributes, normal_attributes, and override_attributes fit in
with the precedence? The person I was talking to on IRC said he was
bit by the same thing.  Or maybe it's just me and I am simply just
reading through the docs too fast.
