From: Joe Perches <joe@...ches.com>
To: linux-kernel@...r.kernel.org
Subject: [PATCH 4/8] scripts/get_maintainer.pl: Use case insensitive name de-duplication
Case insensitive name and email address matching can help reduce
duplication when authors don't always use the exact same signature.
o Add a --interactive per-file exact_match hash so git history
can be checked on per-file only when there is no direct maintainer
o Make @interactive_to list global so save_commits_by_<foo> can check
email names & addresses against this list for duplication
o Don't allow --interactive and --sections
o rename subroutine get_maintainer to get_maintainers
o Added help text option to --interactive menu prompt
Update version to 0.26-beta4
