BIND issue: 2.1.1-bind-loops

(see 
<http://www.webdav.org/bind/draft-ietf-webdav-bind-latest.html#rfc.issue.2.1.1-bind-loops>)

This is a simple clarification: when talking first about the potential 
of bind loops (cycles), state that a server is free to reject requests 
that would create them.

Proposal to add:

"Support for loops is OPTIONAL: servers MAY reject requests that would 
lead to the creation of a bind loop (see DAV:cycle-allowed precondition 
defined in Section 4)."

to the end of Section 2.1.1.
