[PATCH v4 06/10] git-contributors: make revspec required and shebang fix

[Andrey Albershteyn <aalbersh@redhat.com>]

Without default value script will show help instead of just hanging
waiting for input on stdin.

Shebang fix for system with different python location than the
/usr/bin one.

Cut leading delimiter from the final CC string.
