Vim: Fix <Space>, <Return>, ':' and 'Q' in visual mode.
Scripts: Update 'unpack' script to handle files with spaces in their name.
Vim: Make motion God-mode less obtrusive.

Vim: God-mode for word motions, e.g., 'w', 'b', etc.
Vim: God-mode triggered as the key is pressed, don't ignore the first use.
