Always printing both is also okay, but now we run into the issue that
you might have a trailing space if there is no pkerr.

This almost argues that we should have a mode in virCommand where you
can request that stdout and stderr are collected into the same string
(basically, by redirecting stderr onto stdout before doing string
collection); I'll play with that idea.

In the meantime, ACK.  A trailing space isn't the end of the world,
especially if I can get the virCommand changes to work and avoid it in
that way.
