Subject: rebase -i: avoid exporting GIT_AUTHOR_* variables
X-Git-Tag: v1.5.4-rc0~412
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/ae830ed7f50377e64b774ce87441ff4538f04ad7?hp=-c

rebase -i: avoid exporting GIT_AUTHOR_* variables

It is somewhat unsafe to export the GIT_AUTHOR_* variables, since a later
call to git-commit or git-merge could pick them up inadvertently.

So avoid the export, using a recipe provided by Johannes Sixt.

Incidentally, this fixes authorship of merges with "rebase --preserve -i".
