There's a similar function in builtin/tag.c that you are not removing.
You should justify why you are doing this code duplication in the commit
message (or not do code duplication). It might make sense to add a
comment next to match_points_at in tag.c saying stg like "this is
duplicated from ..., will be removed later".


Ok will add this :)
