Subject: [v2 PATCH rfc] scripts/get_maintainer.pl: add interactive mode
This is a first version of an interactive mode for
scripts/get_maintainer.pl .
It allows the user to interact with the script. Each cc candidate can be
selected and deselected and a shortlog of authored commits can be
displayed for each candidate.
The menu is displayed via STDERR, the end result is outputted to STDOUT.
This allows using get_maintainer.pl in interactive mode via
git send-email --cc-cmd.
