The default function name discovery already works quite well for Perl
code... with the exception of here-documents (or rather their ending).

 sub foo {
	print <<END
 here-document
 END
	return 1;
 }

The default funcname pattern treats the unindented END line as a
function declaration and puts it in the @@ line of diff and "grep
--show-function" output.

With a little knowledge of perl syntax, we can do better.  You can
try it out by adding "*.perl diff=perl" to the gitattributes file.
