Re: [PATCH -v3 0/8] fast export/import: handle nested tags, improve incremental exports

Elijah Newren [off-list ref] writes:

This series improves the incremental export story for fast-export and
fast-import (--export-marks and --import-marks fell a bit short),
fixes a couple small export/import bugs, and enables handling nested
tags.  In particular, the nested tags handling makes it so that
fast-export and fast-import can finally handle the git.git repo.

Changes since v2 (full range-diff below):
  - Code cleanup of patch 2 suggested by René

Elijah Newren (8):
  fast-export: fix exporting a tag and nothing else
  fast-import: fix handling of deleted tags
  fast-import: allow tags to be identified by mark labels
  fast-import: add support for new 'alias' command
  fast-export: add support for --import-marks-if-exists
  fast-export: allow user to request tags be marked with --mark-tags
  t9350: add tests for tags of things other than a commit
  fast-export: handle nested tags

Thanks, both.  Replaced.
