This looks less useful than it could be.

	$ git format-patch --stdout -4 >P.mbox
        $ git contacts P.mbox

would have the same number of patches but in a single file.

Wouldn't it be more useful to do something like

	$id = undef;
	while (<$f>) {
		if (/^From ([0-9a-f]{40}) Mon Sep 17 00:00:00 2001$/) {
			# beginning of a patch
			$id = $1;
		}
                next if (!defined $id);
		# inline the body of scan_hunks here...
		if (m{^--- (a/.*|/dev/null)$}) {
			$source = ...
		} elsif (/^@@ -(\d+)...) {
			get_blame();
		}
	}

This change does not seem to account for an invocation without any
argument.  Perhaps write it like so to make it more readable?

	if (!@ARGV) {
		die "No input file?\n";
	}

	for (@ARGV) {
		commits_from_patch(\%commits, $_);
	}
