top: provide for visual hint when overtype mode active

Given that we won't always be able to alter the cursor
shapes (from underscore to block) if in input overtype
mode, this commit will at least provide a visual clue.

[ while this libvte quirk will impact gnome-terminal ]
[ and likely others, we're able to change the cursor ]
[ shape from underscore to block at a linux console. ]
