The option allows someone to run domain-to-native on already existing
domain without the need of supplying their XML. It is basically
wrapper around 'virsh dumpxml | virsh domxml-to-native /dev/stdin'.

Just few things I forgot to sent, so they remained in my drafts folder.

You don't have to do this, you don't use the domain name anywhere, just
the information whether it's present or not.
return false;
- if (virFileReadAll(xmlFile, VSH_MAX_XML_FILE, &xmlData) < 0)

And instead of this, you can just do:
if (vshCommandOptBool("domain") &&
(!(dom = virshCommandOptDomain(ctl, cmd, NULL))))
return false;
+ }
+
+ if (dom) {
+ xmlData = virDomainGetXMLDesc(dom, flags);
xmlData can be NULL after this in case of an error.

+ if (virFileReadAll(xml, VSH_MAX_XML_FILE, &xmlData) < 0)
+ goto cleanup;
+ }
+
+ if (!xmlData) {
So this could just be else {} of the last condition and if xmlData is
NULL after calling virDomainGetXMLDesc(), there should be different
error message.
Other things were pointed out already, I guess.
