 What about tweak the code a bit to match the community proposal[1]
about tag function last year? for Liu's code, that is

1. changing from
   tag_add tag key1 key2 ...
to
   add_tag key tag1 tag2 ...
which may be more common in daily usage,

2. renaming from
   tag_delete
to
   invalidate_tag
which prevents misunderstanding.

I wonder if changes above will help adding this as an experimental
feature in the future release since (i guess) lots of ppl (incl. me)
demand this tag thing so much. :P
