[libvirt] [PATCH] xml: omit domain name from comment if it contains double hyphen

We put a comment containing "virsh edit <domain_name>" at the start of the XML. W3C recommendation forbids the use of "--" in comments [1] and libvirt can't parse it either. This patch omits the domain name if it contains a double hyphen.
