>Description:
According to the dkctl(8), the utility should, when used with the
addwedge command, display "the virtual block device assigned to the
wedge ... after the wedge has been successfully created."
Currently this doesn't happen.

>How-To-Repeat:
Add some wedge with (e.g.)
        dkctl wd0 addwedge swapspace 1048576 1048576 swap
and wonder why there is no output.

>Fix:
Apply the following diff:
