curses and libedit don't play well together. After last year's libedit upgrade in head, they play even less well together. This change resets some curses settings after they get screwed up by libedit calls. Without it, gstat's interactive commands require an extra "enter", screw up the terminal on exit, and screw up the display if the user enters an invalid filter string.
