p4: editorial suggestions

* 2.1 "...avoid confusing cache behaviour." It's not just caches; suggest "...avoid undesired behaviour."

* 3.1 "...instead they MUST respond with the 412 (Precondition Failed) status code."  This is too strong; e.g., what if authentication is needed? Suggest an "unless..." clause allowing other error status codes.

* 3.2 needs a references to "unsafe" in p2.

* 3.4 same problem with MUST respond as 3.1.

* 5 Paragraphs two and three repeat what's been said previously in the document; are they necessary?
