[PATCH/RFC 0/4] Perl rewrite of Ruby git-related

This is a Perl rewrite of Felipe Contreras' git-related v9 patch
series[1] which was written in Ruby. Although that series was ejected
from 'pu'[2], Junio suggested[3,4] that such functionality may be a
useful addition to the official tool-chest, hence this Perl rewrite.

In this submission, the command name has changed to git-contacts since
git-related felt too generic. (git-contacts seemed best of several
possibilities I surveyed: git-people, git-interested, git-mentioned,
git-blame-us.)

This rewrite does not maintain perfect 1-to-1 parity with Felipe's v9
series, however, it is close: minor refactoring was done to eliminate a
small amount of duplicate code; patch files and revision arguments are
allowed in the same invocation rather than being exclusive;
"git cat-file --batch" pipe deadlock is avoided; commit messages are
expanded.

No attempt is made to answer Junio's v9 review[5], as I lack sufficient
insight with '-C' options to be able to respond properly.

My Perl may be rusty and idiomatic usage may be absent.
