 // KeywordProvider uses a TemplateURLService to find the set of keywords.

 // Autocomplete provider for keyword input.
 //
 // After construction, the autocomplete controller repeatedly calls Start()
 // with some user input, each time expecting to receive a small set of the best
 // matches (either synchronously or asynchronously).
 //
 // To construct these matches, the provider treats user input as a series of
 // whitespace-delimited tokens and tries to match the first token as the prefix
 // of a known "keyword".  A keyword is some string that maps to a search query
 // URL; the rest of the user's input is taken as the input to the query.  For
 // example, the keyword "bug" might map to the URL "http://b/issue?id=%s", so
 // input like "bug 123" would become "http://b/issue?id=123".
 //
 // Because we do prefix matching, user input could match more than one keyword
 // at once.  (Example: the input "f jazz" matches all keywords starting with
 // "f".)  We return the best matches, up to three.
 //
 // The resulting matches are shown with content specified by the keyword
 // (usually "Search [name] for %s"), description "(Keyword: [keyword])", and
 // action "[keyword] %s".  If the user has typed a (possibly partial) keyword
 // but no search terms, the suggested result is shown greyed out, with
 // "<enter term(s)>" as the substituted input, and does nothing when selected.
