The whole point of '--uuid' and '--name' options for the existing list commands
is to improve shell scripting with virsh, i.e. avoid having to parse the format
of the table in order to extract some info and/or to call
<prefix>uuid command in a loop for every entry in the table. With your proposal
one would still have to parse the table contents which is in contrast in what
I've just mentioned. Also, this would introduce some inconsistency with how we
currently treat those options with other commands. So this patch will have to
be reworked and while at it, you could also introduce the '--name' option along
with '--uuid'.
