Two bangs will remove the trigger entirely from SnipMate's lookup. In this
case any snippet text is unused.

Three bangs will remove the trigger from the current scope. In this
case any snippet text is unused.

Note: Hard tabs in the expansion text are required. When the snippet is
expanded in the text and 'expandtab' is set, each tab will be replaced with
spaces based on 'softtabstop' if nonzero or 'shiftwidth' otherwise.
