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

@@ Commit message
So, either way nested tags imply the need to delete temporary inner tag
references.
