This is indeed a change from 2616 where we had:

"If the request would, without the If-Match header field, result in 
anything other than a 2xx or 412 status, then the If-Match header MUST 
be ignored." -- 
<http://greenbytes.de/tech/webdav/rfc2616.html#header.if-match>

The change happened between -21 and -22; maybe we should just go back to 
the original text?

 From a quick glance section 5 provides a general overview of how things 
are designed to work; as such the text seems to be useful there. Do you 
see any problems besides the risk of inconsistencies with other text?
