commit: pass author/committer info to hooks
When lying the author name via GIT_AUTHOR_NAME environment variable to "git commit", the hooks run by the command saw it and could act on the name that will be recorded in the final commit. When the user uses the "--author" option from the command line, the command should give the same information to the hook, and back when "git command" was a scripted Porcelain, it did set the environment variable and hooks can learn the author name from it. However, when the command was reimplemented in C, the rewritten code was not very faithful to the original, and hooks stopped getting the authorship information given with "--author". Fix this by exporting the necessary environment variables. Signed-off-by: Junio C Hamano <>
