So here is an attempt to teach "name-rev" a mode that tries to base its name on oldest tag that can reach the commit. It needs the reset_revision_walk() call recently added to the revision traversal API, and applies to bcc0a3e (v1.7.11-rc0~111^2~2) or newer.
Note that this can benefit from caching, as the "weight" of the tag (rather, the commit that is tagged) will never change once a history is made, but that part is left as an exercise to the reader. It correctly names 0136db586c in the kernel history as based on v3.5-rc1 as tags/v3.5-rc1~83^2~81^2~76, not on v3.6-rc1, as we saw on the list recently. Once it is verified to operate correctly and updated to perform properly, we can start passing --weight when "describe --contains" runs the command.
