Subject: filter-branch: preserve and restore $GIT_AUTHOR_* and $GIT_COMMITTER_*
X-Git-Tag: v2.15.0-rc0~48^2~2
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/7b1378bd9547f0842128101a56a64e769a440b37

filter-branch: preserve and restore $GIT_AUTHOR_* and $GIT_COMMITTER_*

These are modified by set_ident() but a subsequent patch would like to operate
on their original values.
