// So, the behaviour we want is this:
// 1. Hide all existing *ng-* attributes from the default list
// 2. Get prefix
// 3. For single completion:
// If no prefix, just display abbreviations
// else if prefix is one of the abbreviations (exact match), add all items for that abbreviation
// (e.g. "ng-" should show all "ng-*" items)
// else if prefix pattern matches an abbreviation (inc. last char), add all items for that abbreviation
// (e.g. "dng-" should show all "data-ng-*" items)
// else if prefix pattern matches an abrreviation, add those abbreviations
// (e.g. "dng" should match "data-ng-" abbreviation. "ng" should match "data-ng-", "ng-" and "x-ng-")
// else if prefix pattern matches an item minus abbreviation, add those items for all abbreviations
// (e.g. "controller" should match "data-ng-controller", "ng-controller", "x-ng-controller")
// else if prefix pattern matches item with abrbeviation, add just those items
// (e.g. "ngc" matches "ng-controller" but not "data-ng-controller". "dnc" matches "data-ng-controller")
// 4. Double completion...
