Sorry, not this time.  The fact that there are two leading + means that
'git diff' really did see two lines, and your second line is flush left
instead of indented (and even still in the copy where you resent with a
better subject line).

The difference is whether you communicate with the libvirtd process
running as root, or with just the session-specific qemu command.  If you
are running unprivileged but attempt to connect to qemu:///system, this
will cause an authentication attempt (you have to supply the root
password); but if the user is only running a qemu:///session, this is
not what they want.

I'm not sure what makes the right thing to do here; hopefully danpb can
shed some better insight into this.
