oliverdain commented on issue #2124: Mango: do not warn about missing index 
when only _id is being selected against

   Hi @wohali . Thanks for the explanation. I've simplified the real query here 
to make the bug report simpler but the real query used `_id` *and* some other 
fields to further limit the results I get. Note that with Mango this is legal 
and if I do that with an index other than `_all_docs` I do not get a warning.
   
   I think the desired behavior isn't "suppress the warning when **only** the 
_id field is being used" but rather something like "suppress the warning when 
the _id field has significantly reduced the set of documents that must be 
examined" or whatever the equivalent rule is for a normal Mango index.
