[PATCH v2 0/2] tag: prevent nested tags

Earlier in the mailing list, Robert Dailey reported confusion over some nested tags. [1]

Peff noted that he hasn't seen a tag-to-a-tag in the wild so in most cases, it'd probably be a mistake on the part of a user. He also suggested we error out on a nested tag unless "--allow-nested-tag" is provided. [2]

This patchset implements those suggestions.

Changes since v1:

* Squashed patches into two patches, one to clean up tag.c, one to do the rest
* s/recursive/nested/g (so the new option is --allow-nested-tag)
* Add more details to --allow-nested-tag documentation
