Re: [PATCH v4 04/19] for-each-ref: add '--points-at' option

 3 & 4 as a single patch may make more sense, if we were to tolerate the
"let's copy & paste first and then later remove the duplicate" as a way to
postpone touching "tag.c" side in order to first concentrate on for-each-ref.

I have not formed a firm opinion on what the right split of the series is, but
so far (assuming that the temporary duplication is the best we can do) what
I am seeing in this series makes sense to me.

Thanks.
