apply two patches from slakmagik that fix a variable test, clean up and fix some the slack-desc information capture, and change the updatelist view from cat to PAGER when using the cli; also, add in a few minor tweaks that attempt to avoid the brief junk seen at the bottom of the screen when moving around the dialog interface; there are still a couple of these left, but this fix gets rid of some of it.
