 It's currently very possible to add custom query vars to the get_comments
 function, for themes and plugins to extend. A problem occurs, however, if
 the function is being used and a custom query var is being used, but no
 standard ones are changing. This is because it caches the first query, and
 every subsequent query is then assumed to be the same since custom query
 vars are ignored.

 I first thought about just using the entire query_vars array for caching,
 but decided there's probably a reason this wasn't done. So instead I
 decided it would make the most sense to make a filter for the cache keys
 so a plugin/theme can add its own keys that should be considered for
