sequencer: load commit related config

phillipwood · gitster · commit b36c59081358 · 2017-11-24T22:44:18.000+09:00
Load default values for message cleanup and gpg signing of commits in
preparation for committing without forking 'git commit'. Note that we
interpret commit.cleanup=scissors to mean COMMIT_MSG_CLEANUP_SPACE to
be consistent with 'git commit'
