Subject: [PATCH] Introduce triple bang syntax to remove triggers

In a snippets file, `snippet!!! foo` will remove the trigger from the
current lookup for the current context. Load order still matters.

This is useful to override a series of triggers with different
descriptions, and turn that into a single trigger, so that you don't
have to choose.

 expanded in the text and 'expandtab' is set, each tab will be replaced with
 spaces based on 'softtabstop' if nonzero or 'shiftwidth' otherwise.
