672 When committing to svn from Git (as part of 'commit-diff', 'set-tree' or 'dcommit'
673 operations), if the existing log message doesn't already have a
674 `From:` or `Signed-off-by:` line, append a `From:` line based on the
675 Git commit's author string. If you use this, then `--use-log-author`
676 will retrieve a valid author string for all commits.
