[PATCH 0/8] Various changes to the "tag" command

This series incorporates and replaces all the "tag" patches I have floating around the list, and adds a lot in the mix which discovered while working on the initial two patches, but which made sense as separate patches.

It's based no top of Jeff's gitster/jk/ref-filter-flags-cleanup.

I'm bundling this all together because a lot of these patches touch the exact same code, and in other cases subsequent patches make use of test suite improvements I made earlier in the series. So although some could be split out entirely (e.g. the --point-at patch), I'd like to just present them all for review together & split out any if there's strong objections to basing them on top of each other.

I think this series changes addresses all the points brought up by Junio/Jeff about my previous patches, except there's no extensive discussion of how the filtering mechanism works in general as pointed out by Junio in <xmqqwpbvumrk.fsf@gitster.mtv.corp.google.com>.

I think it makes sense to have that, but in the interest of getting something out the door I'm not working on that for now.
