X-Git-Tag: v2.15.0-rc0~48

Merge branch 'ic/fix-filter-branch-to-handle-tag-without-tagger'

"git filter-branch" cannot reproduce a history with a tag without
the tagger field, which only ancient versions of Git allowed to be
created.  This has been corrected.

* ic/fix-filter-branch-to-handle-tag-without-tagger:
  filter-branch: use hash-object instead of mktag
  filter-branch: stash away ref map in a branch
  filter-branch: preserve and restore $GIT_AUTHOR_* and $GIT_COMMITTER_*
  filter-branch: reset $GIT_* before cleaning up
