>Description:

"pkg_chk -i" originally just listed a human-readable set of packages which
had changed version.  Now, under the emulation "-u -n", it is also spitting
out pkg_delete commands (because -u would execute them) -- which is
nonintuitive when all the user wants is a human-readable list of changes.

>How-To-Repeat:

pkg_chk -i
  OR
pkg_chk -u -n

>Fix:

Implement some option (-N is taken, so I'm not sure what to use) that not only
suppresses execution of commands, but also suppresses displaying them as well.
Note, "use grep" is not really a reasonable solution, since the format of the
non-executed commands is not guaranteed.  And pkg_chk offered this function
before, so why not...?  :)

Then change -i emulation to use that option, for the temporary compatibility
intent.  Perhaps make the "-i is deprecated" message a little more verbose so
users who have cronjobbed "pkg_chk -i" might notice it more readily.
