Not very likely. The methods that Microsoft used and that are not
in the webdav rfc are all batch-versions of known HTTP/DAV methods:
BCOPY, BDELETE, BMOVE, BPROPFIND, BPROPPATCH. We could make the
actual method a metadata, but that would mean bypassing the normal
http kioslave mechanism in a strange way.

I'll check in the patch.
